# - This module looks for Doxygen and the path to Graphviz's dot
|
|
# Doxygen is a documentation generation tool. Please see
|
|
# http://www.doxygen.org
|
|
#
|
|
# This module accepts the following optional variables:
|
|
#
|
|
# DOXYGEN_SKIP_DOT = If true this module will skip trying to find Dot
|
|
# (an optional component often used by Doxygen)
|
|
#
|
|
# This modules defines the following variables:
|
|
#
|
|
# DOXYGEN_EXECUTABLE = The path to the doxygen command.
|
|
# DOXYGEN_FOUND = Was Doxygen found or not?
|
|
# DOXYGEN_VERSION = The version reported by doxygen --version
|
|
#
|
|
# DOXYGEN_DOT_EXECUTABLE = The path to the dot program used by doxygen.
|
|
# DOXYGEN_DOT_FOUND = Was Dot found or not?
|
|
# DOXYGEN_DOT_PATH = The path to dot not including the executable
|
|

# ===== Rationale for OS X AppBundle mods below =====
|
|
# With the OS X GUI version, Doxygen likes to be installed to /Applications and
|
|
# it contains the doxygen executable in the bundle. In the versions I've
|
|
# seen, it is located in Resources, but in general, more often binaries are
|
|
# located in MacOS.
|
|
#
|
|
# NOTE: The official Doxygen.app that is distributed for OS X uses non-standard
|
|
# conventions. Instead of the command-line "doxygen" tool being placed in
|
|
# Doxygen.app/Contents/MacOS, "Doxywizard" is placed there instead and
|
|
# "doxygen" is placed in Contents/Resources. This is most likely done
|
|
# so that something happens when people double-click on the Doxygen.app
|
|
# package. Unfortunately, CMake gets confused by this as when it sees the
|
|
# bundle it uses "Doxywizard" as the executable to use instead of
|
|
# "doxygen". Therefore to work-around this issue we temporarily disable
|
|
# the app-bundle feature, just for this CMake module:
|
|
if(APPLE)
|
|
# Save the old setting
|
|
SET(TEMP_DOXYGEN_SAVE_CMAKE_FIND_APPBUNDLE ${CMAKE_FIND_APPBUNDLE})
|
|
# Disable the App-bundle detection feature
|
|
SET(CMAKE_FIND_APPBUNDLE "NEVER")
|
|
endif()
|
|
# FYI:
|
|
# In the older versions of OS X Doxygen, dot was included with the
|
|
# Doxygen bundle. But the new versions require you to download
|
|
# Graphviz.app which contains "dot" in it's bundle.
|
|
# ============== End OSX stuff ================
|
|
|
|
#
|
|
# Find Doxygen...
