OpenCV fails to compile in a mixed source project with resources due to conflicting NO macro definition about tuist

[jeffremer]

Interestingly if I remove the top level openCV import in the OpenCVWrapper.mm file attached in the project then it compiles just fine.

So, we have a workaround right now…but this still does feel like a bug, or at least something that would be nice to have more control over.

Hey 👋

Yeah, the SPM integration doesn't use GCC_PREFIX_HEADER and we know using it is not ideal as commented here when we initially added this setting (the PR you linked doesn't actually add that flag, it has been there longer).

The fix should be to use -include flags which is what SPM is doing. As mentioned in the linked comment, I wasn't able to get it working in that PR, but we might need to try another time.

We'll put it into our backlog but if you would like to dive deeper into this one, I'm more than happy to provide guidance and pointers to fix this 👀
