Question

如何从源代码中在CMake中构建OGRE及其唯一的强制依赖（FreeType解决方案），以解决以下错误。 FreeType在Visual Studio 2015中成功编译，但是当我尝试编译OGRE时，它会吐出以下错误。我们将非常感谢您提供的任何帮助。

Answer 1

除了FreeType之外，还有更多依赖项。有一个官方的专用存储库，包含所有相关的，包括zlib：

https://bitbucket.org/cabalistic/ogredeps

克隆/下载并确保OgreMain可以看到它，例如将它放入Ogre源文件夹根目录中名为“Dependencies”的文件夹中。然后它应该被常规的CMake脚本拾取。

Answer 2

您的OgreMain项目未找到文件zlib.h。您需要确保您具有OgreMain包含路径中包含的依赖项include目录，以便它可以找到zlib.h文件。
