    Test: Improve WarnUnusedCliUnused to run on all generators · 4edc0ef3
    Sebastian Holtermann authored
    In the WarnUnusedCliUnused test, the whole CMakeCache.txt was removed in the
    clean stage to trigger the same CMake warning in re-builds.  This technique
    worked only in the Makefile generators and the test was limited to these.
    Now only the variable of interest is removed from the cache by using a
    `unset(UNUSED_CLI_VARIABLE CACHE)` statement in the CMakeLists.txt file.
    This makes the WarnUnusedCliUnused test run on all generators
