I too am having a very similar issue (I think). Here is a bit of the build log where cmake kindly informs me where to go to post about the issue:
```auto
System is unknown to cmake, create:

```
I’m new to the forums and relatively new to cmake. Things started getting complex when I vendor’ed in gRPC (which also uses cmake) as a submodule that I need to link against. Any assistance would be greatly appreciated. Thanks!

If you received the message, then you likely installed the generic “cmake” for gcc instead of the cmake specific to Msys2. For that you need to install “mingw-w64-x86\_64-cmake”

Thanks David, you saved my day, after install the correct cmake version by
```auto
pacman -S mingw-w64-x86_64-cmake
```
It resolves the problem of ‘System is unknown to cmake’.

Hmm, that sort of worked @drankinatty
[https://packages.msys2.org/search?q=cmake](https://packages.msys2.org/search?q=cmake)
```auto
call "C:\msys64""\msys2_shell.cmd" -defterm -no-start -here -mingw32 -c "cmake -DCMAKE_BUILD_TYPE='Debug' .. && cmake --build . && ctest -C 'Debug' && cpack -G 'ZIP' -C 'Debug'"

```
(the same works when `-mingw64` is specified; so is it that MinGW 32-bit variant isn’t supported by CMake?)

Ended up:
```auto
pacman -S --needed base-devel mingw-w64-i686-cmake mingw-w64-i686-toolchain mingw-w64-i686-ninja
```
Which solved the problem (at least with `-G Ninja`)

This problem also exists though I had installed “mingw-w64-x86\_64-cmake”
