# - Finding gtk-doc and building documentation
# This module provides the following function:
#
# GTK_DOC_RUN (
# [ALL]
# [MODULE <module-name>]
# [WORKING_DIR <working-dir>]
# SOURCE_DIRS <source-dir> ...
# [IGNORE_FILES <file> ...]
# [SCANGOBJ <library> [<link-libraries> ...]]
2010-09-13 19:24:53 +02:00
# [{SGML | XML} [<mkdb-output-dir> [<mkdb-options>]]
# [HTML <html-output-dir> <backend-options>]]
# )
#
# The function creates a target named <module-name>_gtkdocize
# which will build the documentation as specified by parameters.
#
# ALL - always build the target
# MODULE - the name of the module
# CMAKE_PROJECT_NAME by default
# WORKING_DIR - path to the working directory
# CMAKE_CURRENT_BINARY_DIR by default
# SOURCE_DIRS - documentation sources
# IGNORE_FILES - ignore these files in the process
# SCANGOBJ - build an object hierarchy scanner
2010-09-13 19:24:53 +02:00
# SGML - make SGML output in the spec. directory
# XML - make XML output in the spec. directory
# HTML - make HTML output in the spec. directory
# (requires either SGML or XML)
#
# Also creates these virtual symbolic outputs if appropriate:
# <module-name>_gtkdocize_scan
# <module-name>_gtkdocize_scan_rebuild_types
# <module-name>_gtkdocize_scan_rebuild_sections
# <module-name>_gtkdocize_scan_gobject
2010-09-13 19:24:53 +02:00
# <module-name>_gtkdocize_mkdb
# <module-name>_gtkdocize_mkhtml
