# - Run Doxygen
#
# Adds a doxygen target that runs doxygen to generate the html
# and optionally the LaTeX API documentation.
# The doxygen target is added to the doc target as a dependency.
# i.e.: the API documentation is built with:
# make doc
#
# USAGE: GLOBAL INSTALL
#
# Install it with:
# cmake ./ && sudo make install
# Add the following to the CMakeLists.txt of your project:
# include(UseDoxygen OPTIONAL)
# Optionally copy Doxyfile.in in the directory of CMakeLists.txt and edit it.
#
# USAGE: INCLUDE IN PROJECT
#
# set(CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR})
# include(UseDoxygen)
# Add the Doxyfile.in and UseDoxygen.cmake files to the projects source directory.
#
#
# CONFIGURATION
#
# To configure Doxygen you can edit Doxyfile.in and set some variables in cmake.
# Variables you may define are:
# DOXYFILE_SOURCE_DIR - Path where the Doxygen input files are.
# Defaults to the current source directory.
# DOXYFILE_EXTRA_SOURCES - Additional source diretories/files for Doxygen to scan.
# The Paths should be in double quotes and separated by space. e.g.:
# "${CMAKE_CURRENT_BINARY_DIR}/foo.c" "${CMAKE_CURRENT_BINARY_DIR}/bar/"
#
# DOXYFILE_OUTPUT_DIR - Path where the Doxygen output is stored.
# Defaults to "${CMAKE_CURRENT_BINARY_DIR}/doc".
#
# DOXYFILE_LATEX - ON/OFF; Set to "ON" if you want the LaTeX documentation
# to be built.
# DOXYFILE_LATEX_DIR - Directory relative to DOXYFILE_OUTPUT_DIR where
# the Doxygen LaTeX output is stored. Defaults to "latex".
#
# DOXYFILE_HTML_DIR - Directory relative to DOXYFILE_OUTPUT_DIR where
# the Doxygen html output is stored. Defaults to "html".
