Is bDebugBuildsActuallyUseDebugCRT supported on Linux?

I’m having an issue with SDL2, and want to check what is happening with SDL_MessageboxValidForDriver and X11_ShowMessageBox. But, when I set bDebugBuildsActuallyUseDebugCRT and bUseCheckedPhysXLibraries to true I keep getting link time errors over libNvClothDEBUG.a not existing. Is there a workaround for not having libNvClothDebug.a?
