# - This module looks for Doxygen and the path to Graphviz's dot
|
|
# Doxygen is a documentation generation tool see http://www.doxygen.org
|
|
# With the OS X GUI version, it 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. This code sets the following variables:
|
|
# DOXYGEN_EXECUTABLE = The path to the doxygen command.
|
|
# DOXYGEN_DOT_EXECUTABLE = The path to the dot program used by doxygen.
|
|
# DOXYGEN_DOT_PATH = The path to dot not including the executable
|
|
# DOXYGEN = same as DOXYGEN_EXECUTABLE for backwards compatibility
|
|
# DOT = same as DOXYGEN_DOT_EXECUTABLE for backwards compatibility
|
|
|
|
# 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 actually placed in Contents/Resources. This is most likely
|
|
# to accomodate people who double-click on the Doxygen.app package and expect
|
|
# to see something happen. However, the CMake backend gets horribly confused
|
|
# by this. Once CMake sees the bundle, it indiscrimately uses Doxywizard
|
|
# as the executable to use. The only work-around I have found is to disable
|
|
# the app-bundle feature for only this command.
|
|
# Save the old setting
|
|
