If you want to specify these paths, don't give the double-precision
libraries as values to the single-precision (*F*loating point) FFTW
variables. Use -DFFTW_INCLUDE_DIR= etc.

Or avoid handling those naming problems yourself and use
-DCMAKE_PREFIX_PATH="/global/software/boost/gcc;$HOME/Programme/fftw3/double"
