Hi
I know that 32-bit OBS is not supported anymore, however I kind of need OBS to run alongside a Pinnacle Dazzle device that only has 32-bit drivers, hence I can only look at a 32-bit OS for now.
Has anyone been able to get the 32-bit version to compile?
I have added the following in the CMakePresets.json file:
but I then get the following errors when running the command cmake --preset windows-x86
Anyone that can help me get a 32 bit ** unsupported ** build?

I have added the following in the CMakePresets.json file:
JSON:

"rhs": "Windows"
},
"architecture": "x86,version=10.0.18362",
"binaryDir": "${sourceDir}/build_x86",
"generator": "Visual Studio 17 2022",

}
}but I then get the following errors when running the command cmake --preset windows-x86
