How to use 2 backends in compilation

[Freziyt223]

Hello, i'm making my game engine and i have a problem i would like to compile imgui with opengl and imgui with vulkan into 2 shared libraries but here comes the problem, zig says that i can only have one build.Module for a file but when i make 2 build.Dependency(to have 2 backends) it says that zig only allows one module per file, so i thought i could just try to import backend.zig file into a program so i'm here to ask will this approach work or do i need to continue thinking about new approaches?

I'm using zig 0.15.2, imporing latest zgui from github with ZON.

If you want to select from multiple backends at runtime, zgui isn't designed for this but you can achieve it by using the no_backend option and then call the backend code manually.
We could export the backend modules from build.zig to help facilitate this.

Thanks, i'll try it. What i thought would be more practical is to have some function that accepts backend as implementation and returns struct to use imgui
