Compiles big binary resources into object code.

The command is defined in the Core component of the Qt6 package, which can be loaded like so:

find_package(Qt6 REQUIRED COMPONENTS Core)

This command was introduced in Qt 5.12.


qt_add_big_resources(<VAR> file1.qrc [file2.qrc ...]
                     [OPTIONS ...])

If versionless commands are disabled, use qt6_add_big_resources() instead. It supports the same set of arguments as this command.


Creates compiled object files from Qt resource files using the Resource Compiler (rcc). Paths to the generated files are added to <VAR>.

This is similar to qt_add_resources, but directly generates object files (.o, .obj) files instead of C++ source code. This allows to embed bigger resources, where compiling to C++ sources and then to binaries would be too time consuming or memory intensive.


You can set additional OPTIONS that should be added to the rcc calls. You can find possible options in the rcc documentation.


set(SOURCES main.cpp)
qt_add_big_resources(SOURCES big_resource.qrc)
add_executable(myapp ${SOURCES})
