# Building YafaRay package
# The build system is kinda 'naive': it hardcodes the PREFIX and other
# directories specified at configure-time into the final libs, so we can't
# specify PREFIX=${PKG}/usr, YF_LIBOUT=${PKG}/usr/lib.. because, when the
# package will be installed, the program will try to find its libraries in a
# /tmp path, and not in /usr/lib/yafaray as it should.
# An easy workaround is to exploit the included debian package creator to
# install all the files in a temporary location without having to specify a
# "fake" PREFIX location. However, this seems to be glitchy too, as specifying
# a different YF_PACKPATH doesn't seem to work fine, so we have to manually
# copy the files from the temporary debian build path to $PKG in the end.
