Question

这里制作文件非常新，所以如果这是一个菜鸟问题，请原谅我。我似乎无法在互联网上找到答案。

我从github分叉了一个公共存储库，它本身应该是下载，制作和运行的存储库，但我已经修复了他们的make文件中的六个错误，试图让它运行。现在我要回到这一点，这似乎与CMake没有找到正确的QT4命令有关。

当我在构建文件夹中时，指令（根据存储库的所有者）说要输入“cmake ..” - 这是对父文件夹中CMakeList.txt的明显引用。文件是hosted on Github，抛出错误的行是第94行，它说：

QT4_ADD_RESOURCES(OFFNAO_RES_SRCS ${OFFNAO_RES})

我正在尝试在Ubuntu 14.04.5上构建这个程序（因为它是最初构建的操作系统，我可以在它工作后进行升级）。它吐出的错误文本是：

CMake Error at CMakeLists.txt:94(QT$_ADD_RESOURCES):
    Unknown CMake command "QT4_ADD_RESOURCES".

- 配置不完整，发生错误！

我安装了qt4-dev-tools（它还安装了所有qt4库）。我似乎无法找到如何让CMake识别QT4及其命令。

我是CMake的新手，这是我第一次遇到QT4，所以我不知道我在寻找什么。如果需要，很高兴提供更多信息。感谢所有帮助。

编辑：这是offnao CMakeList.txt的内容：

此外，声明构建它的README相当模糊，实际上并没有说明从哪个文件夹运行这些命令。它声明：

Welcome to Off-Nao, the rUNSWift debugging toolsuite.

To build this project, either:

You get lucky and bin/build_setup.sh just works :D
(verified under Ubuntu 14.04.1 LTS both natively and in VMs; 
but builds successfully then segfaults at runtime in libGL.so.1
under fresh download of 14.04.3 LTS @ 15/9/2015 
according to gdb - so much for Ubuntu being stable).

---OR--- 
You need Qt4 and probably a bunch of other things like QGLViewer to build it natively:

    $ mkdir build
    $ cd build
    $ cmake ..
    $ make
    $ ./offnao

Once you have performed the steps above once, in future you only need to:

    $ make
    $ ./offnao

In the 'build' directory

我确实得到了LibGL.so.1自述文件中提到的段错误，所以我试图按照下面的说明进行操作。我只能得到“cmake ..”阶段，这就是我得到错误的地方。

Answer 1

重新制定我以前的评论作为答案：

要使用宏QT4_ADD_RESOURCES，QT4_WRAP_UI，QT4_WRAP_CPP等，您需要先在CMakeLists.txt中调用find_package(Qt4 REQUIRED)。请参阅FindQt4.cmake模块（https://cmake.org/cmake/help/v3.0/module/FindQt4.html）的文档。

未知的CMake命令QT4_ADD_RESOURCE
