After three iterations of community review, we believe that this new

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
