Hello,

is there any option to run `fpm build` on multiple CPU threads to speed up the initial build process?  
Basically I’m looking for equivalent of `make -j`.

Thanks for any comments

Not sure what the pre-built versions are compiled with but if you compile and load it yourself with openmp then it runs in parallel. Perhaps a pre-built version should be built with OpenMP. Not sure if any of the available install methods take advantage of that either. @lkedward put that in very early on if memory serves me well. One of the reasons I always build from scratch, so maybe others would like that clarified/available in the various packaging available.
