Yes, I will do that, but the thing that surprised me is that CMake finds this directory at all! It may be something it finds in the registry, but the directory itself has nothing to do with the MS Visual Studio toolchain nor is it a directory that has an obvious connection to GTK (unless you descend deep enough).

Of course, the whitespace issue is a more pervasive one - it has given much more grief over the years than any benefits I can think.
