I don't think this will work the second time you run cmake (i.e., re-run cmake
in an already-initialized build directory) as then this would pick up the
cached value from the previous cmake run.
I think a least magic solution would be to have a cmake option to specify
whether you are overriding the compiler, defaulting to off (and in that case
these cache values would be ignored).
