Building the Polyphone soundfont editor on a Gentoo system

Polyphone is very useful soundfont editor. Version 1.7 compiled without any issues on my Gentoo system once I had edited the polyphone.pro file (one of the source files) and uncommented these lines (taking the initial hash out):

#DEFINES += USE_LOCAL_RTMIDI
#DEFINES += USE_LOCAL_STK
#DEFINES += USE_LOCAL_QCUSTOMPLOT

This stops qmake trying to find the relevant files in your main Gentoo library directories. As it says in the polyphone.pro file:

# Uncomment a line if your distribution doesn't come with some of the following libraries

It is possible to emerge rtmidi (one of the dependencies) from the Gentoo lorelei overlay but Polyphone's installation script still won't find it.

Using the process described here, you end up with a Polyphone binary which works fine.

The version of GCC used was i686-pc-linux-gnu-4.9.3.
