[Openmp-commits] [openmp] r259817 - Add LIBOMP_ENABLE_SHARED option for CMake

[John Mellor-Crummey via Openmp-commits]

To date, libomp has only been dynamic. I wanted static libraries for some platforms, so I generalized the cmake handling to support either static or dynamic. If you want to generalize it to support both, that would be great.
