Hi, I'm getting an error, but I thought I followed the instructions...

$ sudo apt-get install libasound-dev libfreetype6-dev libgl1-mesa-dev libx11-dev libxext-dev libxinerama-dev libxcursor-dev freeglut3-dev libxmu-dev libxi-dev

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
FFTW3F_LIBRARY

...and the same with FFTW3F_THREADS_LIBRARY, and FFTW3_INCLUDE_DIR

I found that installing libfft3f-dev fixed it: sudo apt-get install libfftw3-dev.

So, perhaps add this into the list of packages in the README? (or maybe it's there but my searching didn't find it)

Pop!_OS (Ubuntu variant) 19.04. Feel free to close. Just posting this as FYI.
