Can I build using multiple cores in fortran package manager? Something like the equivalent of make -j4?

From some previous conversations, you need to build the `fpm` with OpenMP enabled. See [here](https://fortran-lang.discourse.group/t/parallel-fpm-builds/10632)

Ah. Unfortunately I installed it via conda.

For what it’s worth, it’s not hard to compile fpm from source. Clone the git repo and then build it with any existing installation of fpm, e.g. from conda:

`fpm build --profile release --flag “-fopenmp”`
