Dear lammps experts,
I am going to install kspace package and I face with this error. How can I find the FFTW3 library?
loading initial cache file /home/lammps-5Jun2019/cmake/presets/minimal.cmake
– Running check for auto-generated files from make-based build system
– checking for module ‘fftw3’
– package ‘fftw3’ not found
– Could NOT find FFMPEG (missing: FFMPEG_EXECUTABLE)
CMake Error at Modules/StyleHeaderUtils.cmake:173 (message):
