#61390 new defect

compiler.openmp_version doesn't set configure.ldflags -L${prefix}/lib/libomp -lomp with port groups cmake+python

Description

compiler.openmp_version 2.5 doesn't set configure.ldflags -L${prefix}/lib/libomp -lomp in a Portfile that also uses port groups cmake and python.

It is necessary to add these flags explicitly to avoid a linking error.

As far as I can tell from reading browser:macports-base/src/port1.0/portconfigure.tcl​, the only thing MacPorts does when you set compiler.openmp_version is pick a compatible compiler and add a port:libomp dependency. Marcus added this support to MacPorts so I'll leave him in charge; I don't know anything about openmp myself.

Should this be assigned to Marcus for comment?
