openmp is enabled. Since mantaflow uses tbb we can safely
disable this flag temporarily for this module.

# Mantaflow triggers a clang-cl compiler error with versions before 9.0.1
# Since mantaflow does not appear to be using OpenMP at this point in time,
# disable the flag for now. See https://bugs.llvm.org/show_bug.cgi?id=43175 for details.
