TEST_LAUNCHER — CMake 3.31.3 Documentation

# TEST_LAUNCHER

Added in version 3.29.

Use the given launcher to run executables. This command will be added as a prefix to `add_test()` commands for build target system executables and is meant to be run on the host machine.

It effectively acts as a run script for tests in a similar way to how `CMAKE_<LANG>_COMPILER_LAUNCHER` works for compilation.

If this property contains a semicolon-separated list, then the first value is the command and remaining values are its arguments.

Contents of `TEST_LAUNCHER` may use `generator expressions`.

This property is initialized by the value of the `CMAKE_TEST_LAUNCHER` variable if it is set when a target is created.
