Yes, you definitely must not assume that a compiler that doesn't have "clang" in its path isn't Clang.

What criteria does CMake use to set CMAKE_C_COMPILER_ID?  Hopefully it's capable of setting it to "Clang" if the 
compiler is Clang, even if the path to the compiler happens to have "cc" or even "gcc" as the last component of the 
path name.

I use autotools - macosx-setup.sh installs them if necessary.  (Apple probably dropped them because they went to GPL 3 
and the last GPL 2 version was getting more and more out of date.)
