# Add a "doc" target with CMake build system. 
# And configure doxy.config.in to doxy.config
#
# target "doc" allows building the documentation with doxygen/dot on WIN32 and Linux
# Creates .chm windows help file if MS HTML help workshop 
# (available from http://msdn.microsoft.com/workshop/author/htmlhelp)
# is installed with its DLLs in PATH.
#
#
# Please note, that the tools, e.g.:
# doxygen, dot, latex, dvips, makeindex, gswin32, etc.
# must be in path.
#
# Note about Visual Studio Projects: 
# MSVS hast its own path environment which may differ from the shell.
# See "Menu Tools/Options/Projects/VC++ Directories" in VS 7.1
