[Scons-users] OpenMP and MPI

I'm working on a program that uses both MPI and OpenMP. gcc and icc require
different compiler flags -openmp / -fopenmp.
Furthermore when using MPI you usually use a compiler wrapper like mpicc /
mpicxx / mpic++ where you don't see the compiler behind.
What's the best scons way to deal with that? Current idea is
if compiler = "g++":
env.Append(CCFLAGS = ['-fopenmp'])
env.Append(LINKFLAGS = ['-fopenmp'])
elif compiler = "icc"
# execute $compiler -show with gives output like that
# g++ -pthread -Wl,-rpath -Wl,/usr/lib/openmpi [...]
# and parse that output
Is using subprocess to execute external processes ok? Any better way?
