我试图建立一个可以与Open Scene Graph（OSG）一起使用的环境，但是我的第三方库有问题。它是使用cmake构建的，但是当我运行它时，会出现多个错误，如下所示：
Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE)
如下所示的线程说这是因为未安装库或cmake找不到它们。
cmake error when configuring
如果只缺少一个库，那很好，但是我有14个库的问题。我正在尝试使用apt-get，然后在.profile文件中输入lib目录，以便cmake可以找到它们。这似乎需要整天才能正确。我是C，C ++和Linux的新手（只需设置我的第一个Ubuntu环境）。在Java中，我可以使用Maven之类的方法来解决此问题。在这种情况下，我可以使用任何类似方法吗？
我已经从github上获取了源代码，并且正在按照他们的指示进行构建。 https://github.com/openscenegraph/OpenSceneGraph。

最佳答案
通常，您会apt-get install openscenegraph。您有理由不能这样做吗？
https://packages.debian.org/jessie/openscenegraph是debian下软件包的名称。根据使用的发行版，您使用本页上列出的要求的条件可能很相似（如果不一致）（另请参见：https://packages.debian.org/jessie/libopenscenegraph-dev）
