CMake的Openscenegraph库的链接

问题描述：

那么，我是CMake的新手，并且想要在eclipse中编辑飞行模拟代码而不是Visual Studio。为此，我下载了Simgear，CMake，Boost库，open scene graph和openalsoft的源代码。CMake的Openscenegraph库的链接

现在我有所有可用的数据，但我不知道在哪里放置这些库的一些。因此，当我运行CMake并参考我的飞行代码时，它抱怨说openscenegraph库没有安装。

请帮助我在哪里需要把所有这些文件，以便使用CMake将我的代码转换为eclipse。我已经安装了boost和openal库。只有问题是openscenegraph库，我把程序文件放在以下路径“C：\ Program Files \ OpenSceneGraph-3.4.0”，但CMake无法访问它。错误代码是

什么**方法**你用来找到OpenAL库[在那个问题]（http://*.com/questions/40373379/compilation-of-flightgear-code-in-eclipse-using-cmake）码功能于使用-cmake的Eclipse的）？你是否尝试过（以及如何）这种OSG库的方法？在CMake下有很多用于开发的库，并且对每个**库有不同的问题......它不是Stack Overflow的目的。 – Tsyvarev

我在Findopenal.cmake中输入了一个代码片段来解决我的库的位置，并且确实有效。我试图对findopenscenegraph.cmake做同样的事情，但它给出了错误......无法找到由“C：/ Program Files/OpenSceneGraph-3.4.0/build”提供的软件包配置文件以下名称： C：/ Program Files/OpenSceneGraph-3.4.0/buildConfig.cmake c：/ program files/openscenegraph-3.4.0/build-config.cmake –

答

我不是一个专家的CMake，这里有些东西我为了在Linux中创建ROS & OSG项目所做的：

添加一个环境变量（如果它现在还没有）的.bashrc文件：

出口PATH = $ {PATH}：.../OpenSceneGraph的-3.4.0/bin中（你的绝对路径）

然后在CMake的文件中加入：

FIND_PACKAGE（OpenSceneGraph的成分osgSim osgUtil osgDB osgFX osgGA osgTerrain osgViewer osgText osgWidget osgManipulator OSG osgShadow）

target_link_libraries（name_of_your_executable $ {PROJECT_NAME} $ {OPENSCENEGRAPH_LIBRARIES}）
