This change has the CMake build system create a dynamic library named libomp instead of libiomp5. Also any reference to libiomp is replaced with libomp. One can still use the LIBOMP_LIB_NAME variable to enforce a different name, and everything will still work as expected. An important note is that libiomp5 and libgomp symlinks are created at install time when on Unix systems. On Windows, copies are created with the legacy names. git-svn-id: https://llvm.org/svn/llvm-project/openmp/trunk@238715 91177308-0d34-0410-b5e6-96231b3b80d8
