qmake Variable Reference

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:

Since the debug option overrides the release option when both are defined in the CONFIG variable, it is necessary to use the debug_and_release option if you want to allow both debug and release versions of a project to be built. In such a case, the Makefile that qmake generates includes a rule that builds both versions, and this can be invoked in the following way:

    make all

Adding the build_all option to the CONFIG variable makes this rule the default when building the project, and installation targets will be created for both debug and release builds.

The following options define the application/library type:

These options are used to set the compiler flags:

These options define specific things on Windows only:

These options only have an effect on Mac OS X:

The build process for bundles is also influenced by the contents of the QMAKE_BUNDLE_DATA variable.

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

    CONFIG += qt console newstuff
    ...
    newstuff {
