CMake build failure on rtosc when liblo is linked on MSVC

Question

I'm trying to build rtosc which uses liblo, ci branch on MSVC. While building, ran into this warning

LINK : warning LNK4044: unrecognized option '/LC:/vcpkg/installed/x64-windows/debug/lib'; ignored [D:\BuildAndGit\zynaddsubfx\rtosc\build\liblo.vcxproj]

which leads to lots of errors

Looked for where /L is being called in cmake and source files but didn't find anything.

Edit: found some more info that -L is a gcc flag and the flag I should be using is /LIBPATH but I still don't know where to look for. Looked for it in all cmake files, didn't find it.
