## Process this file with automake to produce Makefile.in
#
# processing with automake
# will result in a makefile that calls the makefiles for the
# external libraries. 
# (the sourcecode of those libs is included in the gimp-gap distribution
#  to provide compiling and static linking of the required versions that are
#  tested to work with gimp-gap.)
#
# unfortnately those libs are not autotools compatible
# but they should compile on different operating systems with their original makefiles. 
# (at least ffmpeg)
# this workaround integrates those libs into the gimp-gap make concept
# without any changes in the libs.
#
# it creates the libraries via faking scriptdata.
# the libs are installed to GAPLIBDIR ...
# .. but immediate removed in the install-data-hook 
#    (due to static linking there is no need not to install them)
