# Xcode doesn't include OpenMP directly any more, but with these
# flags we can force the compiler to use the libomp we provided
# as a dependency. Normally you can force this on autoconf by
# setting "ac_cv_prog_cxx_openmp" and "LIBS", but this configure
# script does OpenMP its own way so we need to actually edit the script:
