Bug Description

After running the setup for Debian, during compile I got the following error:

[ 87%] Linking CXX executable mixxx
mold: error: undefined symbol: fftw_plan_dft_c2r_1d

try installing the fftw-dev package

As far as I remember, it is already installed.
Edit: True:
fftw-dev ist schon die neueste Version (2.1.5-6build2).
