That work was originally proposed for inclusion in CMake, but it has
been superseded by new builtin features in post-3.0 development.

See the new cmake-compile-features(7) manual:

 http://cmake.org/gitweb?p=cmake.git;a=blob;f=Help/manual/cmake-compile-features.7.rst;hb=4517d6b7

the target_compile_features command:

 http://cmake.org/gitweb?p=cmake.git;a=blob;f=Help/command/target_compile_features.rst;hb=4517d6b7

and the WriteCompilerDetectionHeader module:

 http://cmake.org/gitweb?p=cmake.git;a=blob;f=Modules/WriteCompilerDetectionHeader.cmake;hb=4517d6b7

Of course these won't be available until CMake 3.1 and still require
someone to fill in feature tables for MSVC (currently only GCC and
Clang are supported).
