Good morning :)

It does not like 10.3:

-- Could NOT find OpenMP_C (missing: OpenMP_C_FLAGS OpenMP_C_LIB_NAMES) (found version "1.0")
-- Could NOT find OpenMP_CXX (missing: OpenMP_CXX_FLAGS OpenMP_CXX_LIB_NAMES) (found version "1.0")
CMake Error at cmake/custom_cxxstandard.cmake:52 (message):
  CLANG version must be at least 3.6!
Call Stack (most recent call first):
  CMakeLists.txt:74 (include)


-- Configuring incomplete, errors occurred!

Fixed the clang version for 10.

^ I'm not sure whether hard-depending on one version of clang is a great idea as they get dropped eventually.

^ I think using <bsd.port.pre.mk> (and <bsd.port.post.mk> at the bottom) would be more proper than using <bsd.options.mk>, as you are really not using any option specific stuff here.

I am not sure how this can be solved. Eventually, every specific version will be dropped.

The right way would have been having USES=compiler:clang>3.6.

This already came up before, without a clear solution.

Updated .include to pre/post
Added OPEN_MP=OFF because it can't be found

^ you need += here. After including bsd.pre.mk BUILD_DEPENDS already contains cmake:devel/cmake from the USES=cmake line. Which you override here :)

So this port will fail to configure on FreeBSD < 11, as cmake is not installed.

clang38:lang/clang38 /usr/local/bin/ccache:devel/ccache

Replaced = with += as requested.

Thanks for catching this!
