That's two separate things. This "export" is to export to LLVM. When OpenMP is built standalone, there is no "LLVM" to export to, which I think will cause CMake error. When OpenMP is not built standalone, which means it is built in-tree, there will be a LLVM out there to accept targets.

In your case, you worked around some build issues by forcing `OPENMP_STANDALONE_BUILD` to `TRUE` while in fact it is not.
