Internationalization (build system)

When Qt Extended is configured there are two important variables that are set.

• AVAILABLE_LANGUAGES

  Set to include all detected languages. This variable is used by make lupdate to create .ts files for projects. Third party projects that wish to target a specific set of languages should set this variable.

• LANGUAGES

  Set to include all selected languages. This corresponds to the -languages switch accepted by configure. This variable is used to install .directory files which tell Qt Extended that a given language is available.

Conditional sources need to be specified using the TYPE=CONDITIONAL_SOURCES syntax so that the build system can see the conditional sources and translate them no matter the configuration that is being built.

    FOO.TYPE=CONDITIONAL_SOURCES
    FOO.CONDITION=enable_my_condition
    FOO.HEADERS=foo.h
    FOO.SOURCES=foo.cpp
    !qbuild:CONDITIONAL_SOURCES(FOO)

This mechanism can be used to set the following variables.

• FORMS
• HEADERS
• PRIVATE_HEADERS
• SEMI_PRIVATE_HEADERS
• SOURCES
• RESOURCES
