CMAKE_TEST_LAUNCHER — CMake 4.3.0 Documentation

# CMAKE_TEST_LAUNCHER

Added in version 3.29.

This is a CMake Environment Variable. Its initial value is taken from the calling process environment.

The default value for the `CMAKE_TEST_LAUNCHER` variable when there is no explicit configuration given on the first run while creating a new build tree. On later runs in an existing build tree the value persists in the cache as `CMAKE_TEST_LAUNCHER`.
