mkdir depthai-core/build
cd depthai-core/build
cmake -G Ninja .. -DCMAKE_CXX_ARGS="-std=c++20 -fPIC -Wa,-mbig-obj"

Not sure what is going on but now trying to compile on windows using mingw64, there's 10 pages of cascading errors on that one include file not using proper types.

Hi @onthegrid007,

sorry for the issues but we only test&support the MSVC compiler for windows.
If you manage to resolve the issue, we'd be happy to accept a PR with the fixes.
