That folder is really used for the "make install" step (keeping in mind tat in Linux, the location of executables and libraries is often hardcoded). This is were the final exetuables are copied. This should be distinct from the source directories. I have a /Gimp-Dev directory with a /Gimp-Dev/Build subdir with all the source code and I install things in /Gimp-Dev/Install (so I use $PREFIX=/Gimp-Dev/Install). Other popular choices are "/usr/local" (but it requires "sudo make install") and "/opt/gimp" (the "make install" steps creates the required bin/, lib/, share/ subdirs if necessary).
