Compiles Qt Linguist .ts files into .qm files.
The command is defined in the LinguistTools component of the Qt6 package. Load the package with:
find_package(Qt6 REQUIRED COMPONENTS LinguistTools)
Warning: This function is deprecated. Consider using the target-based functions qt6_add_lrelease or qt6_add_translations instead.
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.
Calls lrelease on each .ts file passed as an argument, generating .qm files. The paths of the generated files are added to <VAR>.
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 before calling qt_add_translation.
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 "${CMAKE_CURRENT_BINARY_DIR}/translations")
qt_add_translation(qmFiles app_en.ts app_de.ts)
Generating helloworld_en.qm, helloworld_de.qm in the build directory:
qt_add_translation(qmFiles helloworld_en.ts helloworld_de.ts)
Generating helloworld_en.qm, helloworld_de.qm in a l10n sub-directory:
set(TS_FILES helloworld_en.ts helloworld_de.ts)
set_source_files_properties(${TS_FILES} PROPERTIES OUTPUT_LOCATION "l10n")
qt_add_translation(qmFiles ${TS_FILES})
