qt_add_translation

Synopsis

qt_add_translation(<VAR> file1.ts [file2.ts ...]
                    [OPTIONS ...])

If versionless commands are disabled, use qt6_add_translation instead. It supports the same set of arguments as this command.

Description

Calls lrelease on each .ts file passed as an argument, generating .qm files. The paths of the generated files are added to <VAR>.

Options

You can set additional OPTIONS that should be passed when lrelease is invoked. You can find possible options in the lrelease documentation.

By default, the qm files will be placed in the current build directory (CMAKE_CURRENT_BINARY_DIR). To change this, you can set OUTPUT_LOCATION as a property of the source .ts file.

For example, with the following code, the .qm files are generated in a translations directory below the current build directory.

set_source_files_properties(app_en.ts app_de.ts
    PROPERTIES OUTPUT_LOCATION "${CMAKE_CURRENT_BINARY_DIR}/translations")

Examples

Generating helloworld_en.qm, helloworld_de.qm in the build directory:

qt_add_translation(qmFiles helloworld_en.ts helloworld_de.ts)

Generating helloworld_en.qm, helloworld_de.qm in a l10n sub-directory:

set(TS_FILES helloworld_en.ts helloworld_de.ts)
set_source_files_properties(${TS_FILES} PROPERTIES OUTPUT_LOCATION "l10n")
qt_add_translation(qmFiles ${TS_FILES})
