Missing $(LINK_OPENMP) in Make/options
LIB_LIBS list in
Make/options should be changed to also contain a reference to
$(LINK_OPENMP). Otherwise, this causes issues when trying to compile and use cfMesh binaries on macOS (in particular, the compiled binaries will fail to dynamically link against OpenMP on launch).
See also: OpenFOAM issue that introduced the
$(LINK_OPENMP) definition, example of an
options file that uses
$(LINK_OPENMP), and bug report for this issue on OpenFOAM.app (macOS).
