I need to build a 32 bit windows version of PCEM. However, the cmake command fails within WINGW32 with "the C compiler identification is unknown" (same message for CXX).
A 64 bit build in WINGW64 runs fine.
cmake, C compilers are all available from within WINGW32.
The cmake command I use is: cmake -G "MSYS Makefiles" -DCMAKE_BUILD_TYPE=Release
The first part of the cmake log shows:
events:
-
kind: "message-v1"
backtrace:
- "C:/msys64/mingw32/share/cmake/Modules/CMakeDetermineSystem.cmake:211 (message)"
- "CMakeLists.txt:3 (project)"

The output was:

Following this are the same messages for the CXX compiler.
Any ideas on how to resolve this (or how to build a 32 bit version from WINGW64)?
