Fix build with CMake 3.18

It looks like CMake 3.18 fixed escaping of `$` in generated Makefiles. It does on FreeBSD, at least, where I had to apply this patch in packaging to get existing QGis packages to build against newer CMake. I'm still checking if this doesn't break with older CMake, though -- I'm fairly confident of the syntax, but you never know until it compiles.
