document hinting of library locations using CMAKE_PREFIX_PATH
The FindFFW3 behavior has been changed to make it more standard. This change removed e.g. the FFTW3_ROOT_DIR env. var. to adhere to the standard CMake way of hinting search locations using the CMAKE_PREFIX_PATH environment variable.
This needs to be documented as well as checked across all custom FindXXX.cmake modules.

I can't find any reference to FFTW3_ROOT_DIR in the documentation. CMAKE_PREFIX_PATH is documented at http://www.gromacs.org/Documentation/Installation_Instructions/Cmake (I just moved it so that it isn't under "Developer" anymore given that it is the only supported with 4.6).
