android-studio - 未设置 Ninja CMAKE_MAKE_PROGRAM 的 ndk 构建错误

Question

我下载了 ndk cmake 和 LLDB 用于 ndk 开发。然后我创建了一个项目
c++代码，应用程序编译出错。

CMake Error: CMake was unable to find a build program corresponding to "Ninja".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.

...

Configuration failed.
External native generate JSON debug: JSON generation completed with problem
FAILURE: Build failed with an exception.

\* What went wrong:
Execution failed for task ':app:generateJsonModelDebug'.
com.android.ide.common.process.ProcessException: Error configuring

Answer 1

我用 Valentin Safonnikov 的评论解决了这个问题:

"Instead changing global path, you can add the path to cmake into local.properties file in the same dir as gradlew. cmake.dir=D\:\\Android\\sdk\\cmake\\3.10.2.4988404"

编辑:我只认为它已解决。当我卸载 cmake 3.10 并只安装 cmake 3.6 时，所有问题才最终得到解决(即使使用 cmake.dir=...\\3.6...，它仍然使用 3.10。我可以在文本 gradle 输出中看到这一点:
