Build and install LMMS from GitHub on RHEL 7

Hi there,

I am running RHEL 7 workstation and want to build and install LMMS from the source code on GitHub. I've been following these directions (https://github.com/LMMS/lmms/wiki/Compiling-lmms), but Qt Creator fails to compile and gives the following message:

I am puzzled because I installed FFTW3, but Qt cannot find it.

Any help would be appreciated, thank you!

Dan
