所以我试图编译一个简单的Ogre3D项目：

C:\OgreSDK\Projects\Physics> cmake -G "MinGW Makefiles" ./

我检查过，在OgreSDK / bin文件夹中我可以看到一个OIS（_d）.dll。如果我尝试设置一个var OIS_HOME，它指向ois.dll中包含dll文件夹的文件夹，它也不起作用。

经过一些尝试后，我编辑了这样的findOIS.cmake：

  # OIS uses the 'includes' path for its headers in the source release, not 'include'
  set(OIS_INC_SEARCH_PATH ${OIS_INC_SEARCH_PATH} ${OIS_HOME}/includes)
endif()

findpkg_finish(OIS)

# add parent of OIS folder to support OIS/OIS.h
add_parent_dir(OIS_INCLUDE_DIRS OIS_INCLUDE_DIR)

# Reset framework finding
set(CMAKE_FIND_FRAMEWORK "FIRST")

这就是CMakeCache.txt中定义的内容：

//Path to a file.

//Path to a file.
OIS_BINARY_REL:FILEPATH=C:/OgreSDK/bin/Release/OIS.dll

//x
OIS_INCLUDE_DIR:PATH=C:/OgreSDK/include/OIS

//x
OIS_LIBRARY_DBG:FILEPATH=OIS_LIBRARY_DBG-NOTFOUND

//x

我编辑了这样的CMakeCache：

OIS_BINARY_DBG:FILEPATH=C:/OgreSDK/bin/Debug/OIS_d.dll

//Path to a file.
OIS_BINARY_REL:FILEPATH=C:/OgreSDK/bin/Release/OIS.dll

//x
OIS_INCLUDE_DIR:PATH=C:/OgreSDK/include/OIS

//x
OIS_LIBRARY_DBG:FILEPATH=C:/OgreSDK/lib/Debug/OIS_d.lib

//x
OIS_LIBRARY_FWK:STRING=NOTFOUND

//x
OIS_LIBRARY_REL:FILEPATH=C:/OgreSDK/lib/Debug/OIS.lib

当我运行make：

λ make
Scanning dependencies of target OgreApp

make[1]: *** [CMakeFiles/OgreApp.dir/all] Error 2

编辑4：好的，我设法运行cmake。但这是我在构建VS 2013和v100编译器时得到的结果：

我正在建造带有VS 2013和Boost的Ogre。成功构建了OgreDeps和Ogre本身，但是在运行SampleDemo.exe时，它说D3DCOMPILER_47.dll丢失，但终于在Steam文件夹中找到它。现在我试图重新编译我的项目

我编译了boost并生成了项目。我在VS 2013中打开它并成功构建了 ALL_BUILD ！但是我该怎么办呢？按钮 Debug 命名为 Attach ... ，当我构建 INSTALL 任务时，它在调试和发布中都给了我

确定VS 2013正在dist中生成OgreApp.exe（或OgreApp_d）。复制此文件夹中的每个Ogre DLL文件并运行exe，它工作:)谢谢你们所有的帮助。 总而言之，解决方案是使用我想要使用的VS版本重建Ogre

为什么不希望先安装pkg-config for Windows？它可以帮助您避免手动入侵CMakefile.txt-s。
您遇到的最后一个错误是由于缺少（正确的）链接Boost.System库的链接器标志。可能，链接的一个或多个库也需要Boost.System，并且这种依赖关系不会自动解决。通常pkg-config用于处理依赖项，但由于您自己动手，因此应使用imported library target手动添加库依赖项。请参阅this tutorial以了解如何将外部预先存在的库正确包含到项目的构建链中。

实际上，在CMakeLists.txt中定义所需的Boost依赖关系的标准方法如下所示：

find_package(Boost 1.50 COMPONENTS program_options locale REQUIRED)

随后的

include_directories(${Boost_INCLUDE_DIRS})
add_executable(an_executable ${AN_EXE_SOURCES})
target_link_libraries(an_executable
  ...
  ${Boost_LIBRARIES}
)

请注意，至少一些链接器（例如GNU ld）无法重新排序给定的库列表，因此如果您的应用程序需要LibA和LibB，而LibB依赖于LibA，那么LibB应该先行在链接库列表中（如果LibA和LibB彼此依赖，则应该包括其中一个库两次）。我不确定问题是否适用于Microsoft VC ++ Linker，但值得一提。

更新：@ Vinz243必须重建OGRE库才能使其与测试应用程序正确链接。
