使用我当前的CMakeLists.txt文件，我可以构建我的项目：

sourceDir>  cmake -G "MinGW Makefiles" .

从源目录。

但是我无法获得树外构建： 

buildDir>  cmake -G "MinGW Makefiles"  ..\MyProg

这是我从 cmake 得到的错误： 

CMake Error at C:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/CMakeMinGWFindMake.cmake:20 (MESSAGE):
  sh.exe was found in your PATH, here:

  C:/Program Files (x86)/Git/bin/sh.exe

  For MinGW make to work correctly sh.exe must NOT be in your path.

  Run cmake from a shell that does not have sh.exe in your PATH.

  If you want to use a UNIX shell, then use MSYS Makefiles.

这些错误来自设置不同的环境是没有意义的。两个命令是否从完全相同的 shell 运行？此外，一旦您配置源内，您就不能进行源外构建。所以，要测试试试这个：

mkdir 新源；在此处查看您的源 mkdir ../build cd ../build cmake -G"MinGW Makefiles" ../newsource

mkdir 内源；在此处查看您的源代码 cmake -G"MinGW Makefiles" 。

从完全相同的外壳执行这两项操作。

我发现了一个肮脏的解决我的问题：

buildDir>  cmake -G "MinGW Makefiles"  ..\MyProg\
buildDir>  cmake -G "MinGW Makefiles"  ..\MyProg\

我第一次收到问题中显示的错误。第二次一切都按原样进行。

如果您有更好、更合乎逻辑的解决方案，请告诉我。

我认为您必须从 Windows PATH 环境变量中删除“MinGW\msys\1.0\bin”。
