Noticed that I forgot to get the x11 and win32 specific display files into the cmake build, so moved them into src/ and added them depending on the target
#
# pidgin_major_ver and pidgin_minor_ver should be defined to match the minimum
# Pidgin API version _required_ to build Guifications
# Due to the way Pidgin checks plugin versions, we need to also ensure that
# the correct minimum version of Pidgin is Require:'d based on what version of
# the Pidgin headers we actually build with.
#
# This allows --define 'pidginver 1' to be used to build an rpm for Pidgin 1.x
