CMake not building MA fortran wrappers

[edoapra]

I could not find any way to build the the MA fortran wrappers in the current CMake infrastructure.
For example, libga.a contains the symbol MA_push_stack, but not MA_push_stack_

I think this is working at this point. It still needs to be tested against NWChem but the symbols all seem to be in libga.a and the header files are getting transferred to the install/include directory. The fortran symbols are not built unless the ENABLE_FORTRAN option is set to ON. Currently, the default for this variable is OFF.
