c++ - 为 CMake 链接 Openscenegraph 库

Question

好吧，我是 CMake 的新手，想在 eclipse 而不是 visual studio 中编辑飞行模拟代码。为此，我下载了 Simgear、CMake、Boost 库、开放场景图和 openalsoft 的源代码。

现在我拥有所有可用数据，但我不知道将其中一些库放在哪里。结果，当我运行 CMake 并引用我的 flightgear 代码时，它会提示没有安装 openscenegraph 库。

请帮助我将所有这些文件放在哪里，以便使用 CMake 将我的代码转换为 eclipse。我已经安装了 boost 和 openal 库。唯一的问题是 openscenegraph 库，我将其放入以下路径“C:\Program Files\OpenSceneGraph-3.4.0”的程序文件中，但 CMake 无法访问它。错误代码为

我不是 CMake 专家，这里是我为在 Linux 中创建 ROS 和 OSG 项目所做的一些事情:

向 .bashrc 文件添加一个环境变量(如果还没有的话):

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

然后在 CMake 文件中添加:

FIND_PACKAGE(OpenSceneGraph 组件 osgSim osgUtil osgDB osgFX osgGA osgTerrain osgViewer osgText osgWidget osgManipulator osg osgShadow)

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