Prefix for CTest ?

Hi all, I’m trying to make a test cache script which will cache outputs of tests and return the cached values if nothing has changed.
Question: Is it possible to prefix the “test executable” in the same manner as with CMAKE_C_COMPILER_LAUNCHER which can be set to “ccache” f.i.?

The add_test calls would need to have this already included and have some way for the build to provide that tool (or find_program can find it on its own).
