## CONFIG

The `CONFIG` variable specifies project configuration and compiler options. The values will be recognized internally by `qmake` and have special meaning. They are as follows.

These `CONFIG` values control compilation flags:

- release - Compile with optimization enabled, ignored if "debug" is specified
- debug - Compile with debug options enabled
- warn_on - The compiler should emit more warnings than normally, ignored if "warn_off" is specified
- warn_off - The compiler should only emit severe warnings.

These options define the application/library type:

- qt - The target is a Qt application/library and requires the Qt header files/library. The proper include and library paths for the Qt library will automatically be added to the project.
- opengl - The target requires the OpenGL (or Mesa) headers/libraries. The proper include and library paths for these libraries will automatically be added to the project.
- thread - The target is a multi-threaded application or library. The proper defines and compiler flags will automatically be added to the project.
- x11 - The target is a X11 application or library. The proper include paths and libraries will automatically be added to the project.
- windows - The target is a Win32 window application (app only). The proper include paths,compiler flags and libraries will automatically be added to the project.
- console - The target is a Win32 console application (app only). The proper include paths, compiler flags and libraries will automatically be added to the project.
- dll - The target is a shared object/DLL.The proper include paths, compiler flags and libraries will automatically be added to the project.
- staticlib - The target is a static library (lib only). The proper compiler flags will automatically be added to the project.
- plugin - The target is a plugin (lib only). This enables dll as well.
- designer - The target is a plugin for Qt Designer.
- uic3 - Configures qmake to run uic3 on the content of FORMS3 if defined, else FORMS.
- no_lflags_merge - Ensures that the list of libraries stored in the `LIBS` variable is not reduced to a list of unique values before it is used.

These options are used to set the compiler flags:

- exceptions - Exception support is enabled
- rtti - RTTI support is enabled
- stl - STL support is enabled

These options define specific things on Windows only:

- flat - When using the vcapp template this will put all the source files into the source group and the header files into the header group regardless of what directory they reside in. Turning this option off will group the files within the source/header group depending on the directory they reside. This is turned on by default.

These options only have an effect on Mac OS X:

- ppc - Builds a PowerPC binary.
- x86 - Builds an i386 compatible binary.
- app_bundle - Puts the executable into a bundle (this is the default).
- lib_bundle - Puts the library into a library bundle.

The `CONFIG` variable will also be checked when resolving scopes. You may assign anything to this variable.

For example:

        CONFIG += qt console newstuff
        ...
        newstuff {
            SOURCES += new.cpp
            HEADERS += new.h
        }

## DEFINES

`qmake` adds the values of this variable as compiler C preprocessor macros (-D option).

For example:

        DEFINES += USE_MY_STUFF QT_DLL

## DEF_FILE

This is only used on Windows when using the `app` template.

Specifies a `.def` file to be included in the project.

## DEPENDPATH

This variable contains the list of all directories to look in to resolve dependencies. This will be used when crawling through `included` files.

## DESTDIR

Specifies where to put the target file.

For example:

        DESTDIR = ../../lib

## DESTDIR_TARGET

This variable is set internally by `qmake`, which is basically the `DESTDIR` variable with the `TARGET` variable appened at the end. The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## DLLDESTDIR

Specifies where to copy the target dll.

## DISTFILES

This variable contains a list of files to be included in the dist target. This feature is supported by UnixMake specs only.

For example:

        DISTFILES += ../program.txt

## DSP_TEMPLATE

This variable is set internally by `qmake`, which specifies where the dsp template file for basing generated dsp files is stored. The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## FORMS

This variable specifies the .ui files (see Qt Designer) to be processed through `uic` before compiling. All dependencies, headers and source files required to build these .ui files will automatically be added to the project.

For example:

        FORMS = mydialog.ui \
            mywidget.ui \
                myconfig.ui

If FORMS3 is defined in your project, then this variable must contain forms for uic, and not uic3. If CONFIG contains uic3, and FORMS3 is not defined, the this variable must contain only uic3 type forms.

## FORMS3

This variable specifies the old style .ui files to be processed through `uic3` before compiling, when `CONFIG` contains uic3. All dependencies, headers and source files required to build these .ui files will automatically be added to the project.

For example:

        FORMS3 = my_uic3_dialog.ui \
             my_uic3_widget.ui \
                 my_uic3_config.ui

## HEADERS

Defines the header files for the project.

`qmake` will generate dependency information (unless `-nodepend` is specified on the command line) for the specified headers. `qmake` will also automatically detect if `moc` is required by the classes in these headers, and add the appropriate dependencies and files to the project for generating and linking the moc files.

For example:

        HEADERS = myclass.h \
                  login.h \
                  mainwindow.h

See also SOURCES.

## INCLUDEPATH

This variable specifies the #include directories which should be searched when compiling the project. Use ';' or a space as the directory separator.

For example:

        INCLUDEPATH = c:\msdev\include d:\stl\include

## LEXIMPLS

This variable contains a list of lex implementation files. The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## LEXOBJECTS

This variable contains the names of intermediate lex object files.The value of this variable is typically handled by `qmake` and rarely needs to be modified.

## LEXSOURCES

This variable contains a list of lex source files. All dependencies, headers and source files will automatically be added to the project for building these lex files.

For example:

        LEXSOURCES = lexer.l

## LIBS

This variable contains a list of libraries to be linked into the project. If you are more comfortable with the Unix convension of -L/-l flags you are free to use them in a cross-platform manner and qmake will do the correct thing with these libraries on Windows (namely this means passing the full path of the library to the linker). The only limitation to this is the library must exist, for qmake to find which directory a -l lib lives in.

For example:

        unix:LIBS += -lmath -L/usr/local/lib
        win32:LIBS += c:\mylibs\math.lib

By default, the list of libraries stored in `LIBS` is reduced to a list of unique names before it is used. To change this behavior, add the `no_lflags_merge` option to the `CONFIG` variable:

        CONFIG += no_lflags_merge

## LITERAL_HASH

This variable is used whenever a literal hash character (`#`) is needed in a variable declaration, perhaps as part of a file name or in a string passed to some external application.

For example:

        # To include a literal hash character, use the $$LITERAL_HASH variable:
        urlPieces = http://doc.trolltech.com/4.0/qtextdocument.html pageCount
        message($$join(urlPieces, $$LITERAL_HASH))

By using `LITERAL_HASH` in this way, the `#` character can be used to construct a URL for the `message()` function to print to the console.

## MAKEFILE

This variable specifies the name of the Makefile which `qmake` should use when outputting the dependency information for building a project. The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## MAKEFILE_GENERATOR

This variable contains the name of the Makefile generator to use when generating a Makefile. The value of this variable is typically handled internally by `qmake` and rarely needs to be modified.

## MOC_DIR

This variable specifies the directory where all intermediate moc files should be placed.

For example:

        unix:MOC_DIR = ../myproject/tmp
        win32:MOC_DIR = c:\myproject\tmp

## OBJECTS

This variable is generated from the SOURCES variable. The extension of each source file will have been replaced by .o (Unix) or .obj (Win32). The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## OBJECTS_DIR

This variable specifies the directory where all intermediate objects should be placed.

For example:

        unix:OBJECTS_DIR = ../myproject/tmp
        win32:OBJECTS__DIR = c:\myproject\tmp

## OBJMOC

This variable is set by `qmake` if files can be found that contain the Q_OBJECT macro. `OBJMOC` contains the name of all intermediate moc object files. The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## PRECOMPILED_HEADER

This variable indicates the header file for creating a precompiled header file, to increase the compilation speed of a project. Precompiled headers are currently only supported on some platforms (Windows - all MSVC project types, Mac OS X - Xcode, Makefile, Unix - gcc 3.3 and up).

On other platforms, this variable has different meaning, as noted below.

## QMAKE_UIC

This variable contains the location of uic if it is not in the path. The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

It can be used to specify arguments to uic as well, such as additional plugin paths. For example:

        QMAKE_UIC = uic -L /path/to/plugin

## RC_FILE

This variable contains the name of the resource file for the application. The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## RCC_DIR

This variable specifies the directory where all intermediate resource files should be placed.

For example:

        unix:RCC_DIR = ../myproject/resources
        win32:RCC_DIR = c:\myproject\resources

## REQUIRES

This is a special variable processed by `qmake`. If the contents of this variable do not appear in CONFIG by the time this variable is assigned, then a minimal Makefile will be generated that states what dependencies (the values assigned to REQUIRES) are missing.

This is mainly used in Qt's build system for building the examples.

## RES_FILE

This variable contains the name of the resource file for the application. The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## SOURCES

This variable contains the name of all source files in the project.

For example:

        SOURCES = myclass.cpp \
              login.cpp \
              mainwindow.cpp

See also HEADERS

## SRCMOC

This variable is set by `qmake` if files can be found that contain the Q_OBJECT macro. `SRCMOC` contains the name of all the generated moc files. The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## SUBDIRS

This variable, when used with the `subdirs` TEMPLATE contains the names of all subdirectories to look for a project file.

For example:

        SUBDIRS = kernel \
              tools

## TARGET

This specifies the name of the target file.

For example:

        TEMPLATE = app
        TARGET = myapp
        SOURCES = main.cpp

The project file above would produce an executable named `myapp` on unix and 'myapp.exe' on windows.

## TARGET_EXT

This variable specifies the target's extension. The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## TARGET_x

This variable specifies the target's extension with a major version number. The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## TARGET_x.y.z

This variable specifies the target's extension with version number. The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## TEMPLATE

This variable contains the name of the template to use when generating the project. The allowed values are:

- app - Creates a Makefile for building applications (the default)
- lib - Creates a Makefile for building libraries
- subdirs - Creates a Makefile for building targets in subdirectories
- vcapp - win32 only Creates an application project file for Visual Studio
- vclib - win32 only Creates a library project file for Visual Studio

For example:

        TEMPLATE = lib
        SOURCES = main.cpp
        TARGET = mylib

The template can be overridden by specifying a new template type with the `-t` command line option. This overrides the template type after the .pro file has been processed. With .pro files that use the template type to determine how the project is built, it is necessary to declare TEMPLATE on the command line rather than use the `-t` option.

## TRANSLATIONS

This variable contains a list of translation (.ts) files that contain translations of the user interface text into non-native languages.

See the Qt Linguist Manual for more information about internationalization (i18n) and localization (l10n) with Qt.

## UICIMPLS

This variable contains a list of the generated implementation files by UIC. The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## UICOBJECTS

This variable is generated from the UICIMPLS variable. The extension of each file will have been replaced by .o (Unix) or .obj (Win32). The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## UI_DIR

This variable specifies the directory where all intermediate files from uic should be placed. This variable overrides both UI_SOURCES_DIR and UI_HEADERS_DIR.

For example:

        unix:UI_DIR = ../myproject/ui
        win32:UI_DIR = c:\myproject\ui

## UI_HEADERS_DIR

This variable specifies the directory where all declaration files (as generated by uic) should be placed.

For example:

        unix:UI_HEADERS_DIR = ../myproject/ui/include
        win32:UI_HEADERS_DIR = c:\myproject\ui\include

## UI_SOURCES_DIR

This variable specifies the directory where all implementation files (as generated by uic) should be placed.

For example:

        unix:UI_SOURCES_DIR = ../myproject/ui/src
        win32:UI_SOURCES_DIR = c:\myproject\ui\src

## VERSION

This variable contains the version number of the library if the `lib` TEMPLATE is specified.

For example:

        VERSION = 1.2.3

## VER_MAJ

This variable contains the major version number of the library, if the `lib` template is specified.

## VER_MIN

This variable contains the minor version number of the library, if the `lib` template is specified.

## VER_PAT

This variable contains the patch version number of the library, if the `lib` template is specified.

## VPATH

This variable tells `qmake` where to search for files it cannot open. With this you may tell `qmake` where it may look for things like SOURCES, and if it finds an entry in SOURCES that cannot be opened it will look through the entire VPATH list to see if it can find the file on its own.

See also DEPENDPATH.

## YACCIMPLS

This variable contains a list of yacc source files. The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## YACCOBJECTS

This variable contains a list of yacc object files. The value of this variable is typically handled by `qmake` or qmake.conf and rarely needs to be modified.

## YACCSOURCES

This variable contains a list of yacc source files to be included in the project. All dependencies, headers and source files will automatically be included in the project.

For example:

        YACCSOURCES = moc.y
