Why does c std::mutex error occur during makefile gtest?

Question

C++ / C#

Here is the error output:

PS C:\Users\79306\Documents\GitHub\2DPrimitiveLib\tests><i> mingw32-make</i>

   std::mutex mu_;
        ^~~~~
...

Then everything also breaks down, probably because of the first breakdown (c std::mutex).
I tried to build a makefile with Cmake-a with the gtest_disable_pthreads flag, but the errors continue to fly out:

I installed pthreads from the batch installer, but it still does not work.
Here are the CMake settings:

C++ compiler retired, or not configured C++ >= C++11
- check if compiler is new (GCC 11 or Clang 12)
- add flag -std=c++17
