I don't get it.  Why do you need to resolve any of this at runtime?
Resolve it 5 times at configuration time, run 5 different
configurations.  It would be 10 lines in your favorite scripting
language.  Could invoke with "cmake -P mybuildscript" if you don't
mind CMake script and don't want another language dependency.
