fftw custom install autodetection

[simonlegrand]

Hello,

I tried to compile ff (on a HPC cluster) against an existing fftw made visible through environment variables (FFTW_ROOT and FFTW_DIR) but configure doesn't seem to see it. I noticed there are no way to explicitly pass the fftw path to the configure script (--with-fftw). Is there a way to achieve this?

Regards,

There is no way to pass those flags to configure currently, so it's not possible.

Thanks for the answer!
