Speed up build with DAGMC #583

Open aprilnovak opened 1 year ago

aprilnovak commented 1 year ago

The build with DAGMC enabled is kind of slow - I think CMake/make isn't correctly recognizing that it doesn't need to rebuild the DAGMC tools every time, or Pyne is somehow interfering, because I spend about ~2 minutes or so on a few objects like this, even when no files have been changed since the last build:

@pshriwise what do you think about setting BUILD_UWUW off? Based on Aurora's code, I think I'd need to do special C++ code in Cardinal to support the UWUW route anyways, that we don't have.
