mingw w64 gcc/g++ platform

System is unknown to cmake, create:
Platform/MINGW64_NT-10.0-18363 to use this system, please post your config file on discourse.cmake.org so it can be added to cmake

For reference, the message posted above comes from this code in CMake. It occurs when CMake detects a CMAKE_SYSTEM_NAME that is not known.

MinGW is known, but the CMAKE_SYSTEM_NAME detected should not be MINGW64_NT-10.0-18363. We need to figure out how that name is detected. What version of CMake are you using?

I was using msys/cmake from msys2

it works fine with mingw-w64-x86_64-cmake, and the mingw-w64 toolschain
sorry for nois, and hope that could help someone
