Not a full path to an existing c

记录一个在开发中遇到的错误。导致这个错误的原因是同时给我的NDK是Windows的，而我用的Mac开发。

Caused by: com.android.builder.errors.EvalIssueException: /Users/liuhai/Documents/projecttest/mpos_terminal/corelib/CMakeLists.txt : C/C++ debug|arm64-v8a : CMake Error in CMakeLists.txt:
  The CMAKE_C_COMPILER:

    /Users/liuhai/Library/Android/sdk/ndk/android-ndk-r16b/toolchains/llvm/prebuilt/darwin-x86_64/bin/clang
  is not a full path to an existing compiler tool.

  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH.
