Pre and Post Build Steps with VS2015

I'm converting some DLL projects that I previously built using VS2005. Most of them have some kind of pre or post build events defined. VS2005 had a useful feature whereby for a build (as distinct from a rebuild) the target file would be evaluated (i.e. the target DLL in my case) and if it didn't need to get built, the whole build process would get skipped.

But VS2015 is different... even if there's no reason to build the target DLL, VS2015 insists on running the pre and post build steps. Is there any way to turn off this feature (i.e. make it work like it used to work in VS2005)?
