# This file contains the following macros:
#
# NEPOMUK_GENERATE_FROM_ONTOLOGY
# Parameters:
# ontofile - Path to the NRL ontology defining the resources to be generated.
# targetdir - Folder to which the generated sources should be written.
# out_headers - Variable which will be filled with the names of all generated headers.
# out_sources - Variable which will be filled with the names of all generated sources.
# out_includes - Variable which will be filled with complete include statements of all
# generated resource classes.
#
# In addition to the parameters an arbitrary number of template filenames can be set as arguments
#
# In case of success NEPOMUK_RESOURCES_GENERATED is true, otherwise false
