《OpenSceneGraph三维渲染引擎设计与实践》源码用Cmake编译时遇到的问题

wangan2010

最经正在看王锐先生写的《OpenSceneGraph三维渲染引擎设计与实践》，然后通过SVN提取出源代码，但是用Cmake进行编译时，出现如下提示：

应该如何设置才能让她们自动寻找对应的位置，我的OSG存放路径为C:\OSG
感觉要是自己一个个的设置路径的话就太麻烦了!
小弟在此先提前感谢各位大侠指点

看看它的CMakeModel中查找OSG的find文件是怎么写的吧，看看是不是需要指定什么环境变量

非常感谢版主的回答，我看了一下CmakeModel中的Findosg.cmake 。它里面的内容如下：
#
# NOTE: It is highly recommended that you use the new FindOpenSceneGraph.cmake
# introduced in CMake 2.6.3 and not use this Find module directly.
#
# 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 osg
# This module defines
#
# OSG_FOUND - Was the Osg found?
# OSG_INCLUDE_DIR - Where to find the headers
# OSG_LIBRARIES - The libraries to link against for the OSG (use this)
#
# OSG_LIBRARY - The OSG library
# OSG_LIBRARY_DEBUG - The OSG debug library
#
# $OSGDIR is an environment variable that would
# correspond to the ./configure --prefix=$OSGDIR
# used in building osg.
#
# Created by Eric Wing.

# Header files are presumed to be included like
# #include <osg/PositionAttitudeTransform>
# #include <osgUtil/SceneView>

include(Findosg_functions)
OSG_FIND_PATH   (OSG osg/PositionAttitudeTransform)
OSG_FIND_LIBRARY(OSG osg)

include(FindPackageHandleStandardArgs)
FIND_PACKAGE_HANDLE_STANDARD_ARGS(osg DEFAULT_MSG OSG_LIBRARY OSG_INCLUDE_DIR)


是否应该在其基础上进行修改？
CmakeModel文件家中还有FindosgText.cmake  FindosgDB.cmake等.cmake文件，是否也都应该进行修改？
谢谢！

设置一个环境变量名为OSGDIR并且设置为您的OSG安装路径就可以自动查找了

之后是否只要用VS打开生成的“osgEngineBook.sln”然后选择生成_批生成，选择ALL_BUILD的Debug和Release进行生成，之后再对INSTALL的Debug和Release进行生成？

实验就可以了，基本上就是这个意思
