[ft-devel] Suggest not modifying ftoption.h in source

[Stuart Mentzer]

Hello,

Currently the freetype CMake build process modifies the ftoption.h
header in the source tree to uncomment defines for options like PNG
support. This is problematic for automated build processes since it
requires a source refresh step between builds that won't be obvious
to people building the first time.

Ideally, all custom headers would be written to and found in the
build tree. Short of that, the build process at least needs to be
bidirectional in that it can re-comment any uncommented defines
from the last build for features NOT enabled.

Thanks for considering this suggestion.

Stuart
