CMAKE buld system should meet everyone's requirements. Enhanced CMake Build System Commit * Supports Linux, Mac, Windows, and Intel® Xeon Phi builds * Supports building with gcc, icc, clang, and Visual Studio compilers * Supports bulding "fat" libraries on OS/X with clang * Details and documentation on how to use build system are in Build_With_CMake.txt * To use the old CMake build system (corresponds to CMakeLists.txt.old), just rename CMakeLists.txt to CMakeLists.txt.other and rename CMakeLists.txt.old to CMakeLists.txt llvm-svn: 214850
