#
# add_error_files(_part _file0)
#    Adds build and install rules to create .error files from .error.xml
#    files in the current source directory. The _file0 is expected to be
#    without the .xml extension. The macro can receive one or more error
#    files. There is created a custom "${_part}-error-files" target.
#
# add_eplug_file(_part _eplug_filename)
#    Adds build and install rules to create .eplug files from .eplug.xml
#    files in the current source directory. The _eplug_filename is expected
#    to be without the .xml extension. The macro can receive exactly one
#    eplug file. There is created a custom "${_part}-eplug-file" target.
