Describe the bug
This project doesn't build on Windows/MinGW

To Reproduce
Build as normal:

1. git clone
2. mkdir build && cd build
3. cmake .. / cmake -G 'MinGW Makefiles' ..
4. ninja / make -j$(nproc)

• Results when building with MSYS2 UCRT64 GCC here
  • Results when enabling big objects and disabling tests here
• Results when building with MSYS2 CLANG64 Clang here
  • Results when using same flags as on UCRT64 here

In between all these 4 runs, I clean out the build directory.

Expected behavior
Build on Windows/MinGW, as it does on Linux and Windows/Cygwin

Additional context
Tested using MSYS2 UCRT64, CLANG64, and MSYS environments, using their respective mingw-* and Cygwin GCC/Clang, CMake, Make, and Ninja packages
