在 Eclipse CDT 和 Cygwin Windows 上使用 CMake

Question

对于一个新项目，我们想使用 CMake。我们正在使用 Eclipse CDT 作为 IDE 和 Cygwin gcc.

我们生成了 CMakeLists.txt 并遵循了 [本教程（选项 2）][1]。

当我尝试运行所描述的 Make 目标以使用 CMake 生成 Makefile 时，它执行

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 控制台运行命令它工作得很好，但是我还必须运行从 Cygwin 控制台 make，因为 Makefiles 是用 Unix 路径生成的。

编辑：

所以我解决了这个问题（见下面我的回答）。

但我仍然遇到问题。

当我按照教程中的建议尝试运行 CMake 作为 Eclipse 中的 Make 目标时，出现以下错误：

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

似乎出于某种原因 CMake 假设我有一个 MinGW 环境而不是 Cygwin。

EDIT2 假设是 MinGW 系统，因为 Git 安装在 Cygwin 之前的 PATH 中并且使用了 Git 的 uname 命令（returns MinGW）。

Answer 1

如果您在 Eclipse 的 Make 对话框中选中 "Make Target - Same as the target name"，Eclipse 将添加一个

Run CMake

命令（参见问题），CMake 对其进行了错误解释。我刚刚取消选中 "Same as the target name".
