CMake module for finding FFTW 3 using find_package
License: BSD 3-Clause "New" or "Revised" License
Hello,
i compiled and installed fftw3 in ~/LIBS/fftw-3.3.10. I'm using cmake as noted in your README, but i got the message:
cmake -DFFTW_ROOT=~/LIBS/fftw-3.3.10 ..
...
-- Build files have been written to: /home/me/AMUbox/projets/modelisation-simujura/build/findFFTW-download

-- Could NOT find FFTW (missing: FLOAT_LIB FLOAT_OPENMP_LIB)
FFTW not found
i notice that fftw3 comes with pkg-config file, is it possible to use it to find FFTW with cmake? it seems necessary to set PKG_CONFIG_PATH to dir given by FFTW_ROOT and the reult will be:
$ pkg-config --libs fftw3
-L/home/me/LIBS/fftw-3.3.10/lib -lfftw3
Thanks for help
Gérard
I want to add a test suite on which FFTW is installed/compiled with all the possible options and FindFFTW tries to find them from CMakeLists.txt files. This suite should then run on CI, I think GitHub Actions would be best.
As mentioned in #3 (comment), I think this will make adding new features like #3 a lot easier.
