I wouldn't go that far given that /usr/bin/clang++ and cmake call the 
same compiler.
If you were to use a compiler in a custom installation prefix (without 
apple's tool in between) and would pass that to CXX the compiler would 
be used as-is.

CXX is honored even if the path is not preserved.

Given that /usr/bin/clang++ on the build system and /usr/bin/clang++ on 
a client system may not actually call the same compilers does it even 
make sense to record and use it as-is?
