>From the cmake sources (Modules/CMakeCCompilerId.c.in):

...
#elif defined(__clang__)
# define COMPILER_ID "Clang"
# define COMPILER_VERSION_MAJOR DEC(__clang_major__)
# define COMPILER_VERSION_MINOR DEC(__clang_minor__)
# define COMPILER_VERSION_PATCH DEC(__clang_patchlevel__)

#elif
...

So this is the reliable detection method.

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
