[Openmp-dev] Initial Intel Cmake Build System Patch

[Jack Howarth]

Jonathon,
     Thanks. Confirmed to work properly on x86_64-apple-darwin12 with…

% cd runtime
% mkdir build
% cd build
% cmake -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -Dos=mac
-Darch=32 ..
% make all common
% file libiomp5.dylib
libiomp5.dylib: Mach-O dynamically linked shared library i386

and

% cd runtime
% mkdir build
% cd build
% cmake -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -Dos=mac
-Darch=32e ..
% make all common
% file libiomp5.dylib
libiomp5.dylib: Mach-O 64-bit dynamically linked shared library x86_64

Are there any plans to tweak this to automate the build of a fat
libiomp5.dylib on darwin?
