Question

对于我们想要使用CMake的新项目。我们使用Eclipse CDT作为IDE和Cygwin gcc。

我们生成了CMakeLists.txt并遵循[本教程（选项2）] [1]。

当我尝试运行描述的Make目标以生成带有CMake的Makefile时，执行

cmake -E chdir C:/projects/eclipse_ws/MyApp/Build/ cmake -G "Unix Makefiles" ../ Run CMake

我收到错误

CMake Error: The source directory "C:/projects/eclipse_ws/MyApp/Build/CMake" does not exist.

如果我直接从Cygwin控制台运行命令它运行正常，但是我必须从Cygwin控制台运行make，因为Makefile是用Unix路径生成的。

修改

所以我解决了这个问题（请参阅下面的答案）。

但我仍然遇到问题。

当我尝试按照教程中的建议在Eclipse中运行CMake作为Make目标时，我收到以下错误：

cmake -E chdir Build/ cmake -G 'Unix Makefiles' ../

似乎因为某种原因，CMake假设我有一个MinGW环境，而不是Cygwin。

EDIT2 假设MinGW系统，因为在使用Cygwin和Git的uname命令（返回MinGW）之前，Git安装在PATH中。

Answer 1

如果在Eclipse的Make对话框中选中“Make Target - 与目标名称相同”，Eclipse将添加

Run CMake

命令（见问题），由CMake误解。我只是取消选中“与目标名称相同”。

在Windows上使用CMake和Eclipse CDT以及Cygwin
