Recently I cannot build in double precision anymore, everything builds for single precision.
This is the make output:

CMakeCache has the following part about fftw:
//Path to a file.
FFTW3F_INCLUDE_DIR:PATH=/usr/include

//Path to a library.
FFTW3F_LIBRARIES:FILEPATH=/usr/lib64/libfftw3f.so

//Path to a file.
FFTW3_INCLUDE_DIR:PATH=/usr/include

//Path to a library.
