我有一个在构建过程中被克隆(使用 git)的 ExternalProject 依赖项。这一切都适用于 CMake + Make。

mkdir build && cd build; 
cmake ..
make

当我键入 make 时,它​​使用 git 正确克隆和构建库。

但是,当我使用 Ninja Generator 时:

mkdir build && cd build; 
cmake -GNinja ..
ninja

我收到以下错误:

$ cmake -GNinja ..                                                                                                                                                                                                                                                   -- The C compiler identification is AppleClang 6.0.0.6000054

cmake+ninja组合不支持git下载外部项目吗?

事实证明,如果您在构建之前进行清理,一切正常,并且 ninja 确实会正确下载我的依赖项。

所以工作流程看起来像这样:

mkdir build && cd build
cmake -G Ninja ..
ninja clean  # if you don't do this, it will not download Externalproject dependencies
ninja

一定是忍者生成器中的某种错误,但我现在对这个工作流程很满意。
