Thank you for your help. Argh, this one is tricky. It's not an isolated build with pip, just a regular CMake build. I wonder if I should manually remove the...

Ok, with GNU compilers there is an unconditional search for OpenMP in the FFTW heFFTe logic, let me add those for linux to the dependencies: https://github.com/icl-utk-edu/heffte/blob/v2.4.0/cmake/FindHeffteFFTW.cmake#L78-L80

I think the FFTW library is overlinking in the `FindHEFFTW.cmake` the FFTW library variants... this looks too much to me - threads and OMP versions at the same time? ```...

That is possible, I myself do some quite elaborate back-and-forth when searching for FFTW downstream in other codes: https://github.com/ECP-WarpX/WarpX/blob/development/cmake/dependencies/FFT.cmake @mkstoyanov do you have any recommendations on how to build heFFTe...

Thanks, @mkstoyanov! I now started a patch to make the FFTW threads search in heFFTe's CMake logic more robust: https://github.com/icl-utk-edu/heffte/pull/55 ~~I am trying to find out: is FFTW thread support...

@egpbos @jakirkham we made it - heFFTe ready for review & merge :)

Oops, sorry 😅 @conda-forge/help-c-cpp heFFTe package is ready to gooo 🚀

Thank you, Isuru!

@dsame thank you for the hint! Can you tell me what else I need in the virtual environment besides `-T "ClangCl"` to find this OpenMP install with CMake? I am...

I think I found a way by using the Ninja generator :tada: ```yml build_win_clang: name: Clang w/ OMP runs-on: windows-2019 steps: - uses: actions/checkout@v2 - uses: seanmiddleditch/gha-setup-ninja@master - name: Build...
