Most likely, you do not need a custom-compiled fftw.
Take a look in the Dockerfile for your distro to see, what packages we  install 
for the automated testing.
https://github.com/espressomd/docker/tree/master/docker

You may also need to take your custom installation of the fftw out of the 
library and include search paths or explicitly select the one shipped with the 
distro in CMake. The stuff in /usr/local typically takes precedence over the 
stuff coming from your distro.
