Changes to CMakeLists.txt are not detected

[l0calh05t]

Steps to reproduce:

• Create a CMake project
• Configure using cmake (and FASTBuild generator)
• Optional: Build project
• Make changes to CMakeLists.txt and source files so that build fails if no reconfigure occurs
• Build project

Result:

Build fails, as fbuild.bff is not updated.

Agreed - currently there is no detection for a CMakeList.txt file that is out of date.
I don't believe this is a feature supported by all CMake generators - I'm not sure when fastbuild generator would be able to support this, as fastbuild would need to be able to allow it's current script file to be reloaded/restarted.

So far this is the first one I have encountered with this behavior. It works with Makefiles, MinGW Makefiles, NMake, all VS generators from 2008-2015 and Ninja. The VS generators typically don't reload automatically, so that isn't really an issue, but it would of course be nice.
