The cmake options ENABLE_TESTS, BUILD_DOXYGEN,BUILD_SPHINX don't do anything

It seems that ENABLE_TESTS should be a condition for this section?

#if (NOT ENABLE_PSI4)
    # test suite
    enable_testing()
    include(CTest)
    add_subdirectory(test)

    # sample suite
    add_subdirectory(samples)
#endif()
