我是使用CMake的新手（对于C++来说，对于Makefiles，C，&来说是相当新的）。我的任务是将我们当前的构建系统更改为使用CMake生成Makefiles并编译我们的代码的系统。我很难破译CMake报告的错误，并且没有运气搜索这个网站或任何sute。如果这个问题已经在其他地方得到解答，请直接告诉我，我会提前通知你。解密CMake错误
我曾试图发布显示我们当前文件结构的破坏的形象，但我没有信誉点张贴图片...
下面是我在同时运行接收错误cmake。 & 使：

“expatfiles.txt只是列出了expat所需的源文件”不这样做。 CMake无法检测到这个文件的变化，所以如果你修改它，cmake将不会自动构建新添加的文件。只需在相应的CMakeLists.txt中列出它们即可。 – SirDarius
您看到的错误是'make'错误，而不是'cmake'错误，这些错误看起来像来自编译器。你可能想检查你的源代码。 – SethMMorton
