While configuring Spirit, I had already loaded the FFTW environment using the module, yet Spirit failed to recognize it. Consequently, I ventured into the CMakeLists to locate the section pertaining to FFTW settings, only to find configurations related solely to C++. In response, I manually inserted set( FFTW_LIBRARIES "/public/software/mathlib/fftw/openmpi/3.3.9_double/lib" ), but alas, the FFTW library remained unrecognized.
-- Could NOT find FFTW (missing: FFTW_LIBRARIES)
CMake Warning at core/CMakeLists.txt:242 (message):
Could not find any FFTW libs -> Using kissFFT fallback
-- >> Using kissFFT
CMake Warning at core/CMakeLists.txt:258 (message):
Using kissFFT together with OpenMP. If you intend to perform calculations
including dipole-dipole interactions with OpenMP it is strongly
recommended to use FFTW instead!
