Missing -lpthread

On FreeBSD 13 version 3.1.0 breaks:

Thanks for reporting.
It seems as if we need to update our condition when to add pthread to the list of linked libraries (cf. https://github.com/cginternals/glbinding/blob/master/cmake/CompileOptions.cmake#L157).
What is the value of CMAKE_SYSTEM_NAME on your system? I assume it should be FreeBSD?
