- The find_* commands now provide a HINTS option.
- The option specifies paths to be preferred over the system paths.
- Many Find* modules were using two find calls with NO_DEFAULT_PATH
to approximate the behavior, but that blocked users from overriding
things with CMAKE_PREFIX_PATH.
- This commit uses the HINTS feature to get desired behavior in
only one find command call.

# This is part of the Findosg* suite used to find OpenSceneGraph components.
|
|
# Each component is separate and you must opt in to each module. You must
|
|
# also opt into OpenGL and OpenThreads (and Producer if needed) as these
|
|
# modules won't do it for you. This is to allow you control over your own
|
|
# system piece by piece in case you need to opt out of certain components
|
|
# or change the Find behavior for a particular module (perhaps because the
|
|
# default FindOpenGL.cmake module doesn't work with your system as an
|
|
# example).
|
|
# If you want to use a more convenient module that includes everything,
|
|
# use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

|
# Locate osgShadow
|
|
# This module defines
|
|
# OSGSHADOW_LIBRARY
|
|
# OSGSHADOW_FOUND, if false, do not try to link to osgShadow
|
|
# OSGSHADOW_INCLUDE_DIR, where to find the headers
|
|
#
|
|
# $OSGDIR is an environment variable that would
|
|
# correspond to the ./configure --prefix=$OSGDIR
|
|
# used in building osg.

# Header files are presumed to be included like

# #include <osg/PositionAttitudeTransform>
