Create a sample project that needs OpenMP:

Hi Adriaan,
I tried several ports that were breaking because of OpenMP. With this patch
they detect OpenMP okay now.
Thank you for fixing this!

Yuri, here's a patched-up FindOpenMP.cmake (and the diff between the one
included with cmake-3.13.3 and the patch-up version). It basically hits things
with a hammer again until stuff works.

For CMake 3.11, a new issue is introduced where `find_package(OpenMP)` does the
right thing and finds -fopenmp as the right flag, and then it goes looking for
supporting libraries. With CMake 3.11,

@adriaan I had a look through the cmake ports description and noticed you

Okay, that was my understanding of it as well. I couldn't check myself

I've looked more closely at the `devel/openmp` port:
- it installs ${LOCALBASE}/include/omp.h
- it installs ${LOCALBASE}/lib/libomp.so

@christian, clang -fopenmp itself works, e.g.:

On 12-CURRENT amd64, base clang will find OpenMP if I add
`-DCMAKE_CXX_FLAGS="-I/usr/local/include -L/usr/local/lib"` (which makes sense,
given that OpenMP is found in $LOCALBASE). So it may be suffi

Does base clang support OpenMP (ever?). I just tried on a 10.4 box; complete
logs are in the upstream bug report, but basically:
