[CMake] add_dependencies behaviuor

[Tyler]

This looks reasonably correct to me (although PreBuildCommands has no
explicit dependency on the MyTool target; I'm not sure if the fact
that you're calling MyTool as part of your custom target will cause
CMake to create an implicit dependency from PreBuildCommands to
MyTool).

What is the problem that you're seeing? Can you show us some output
from a build that demonstrates this problem?

The next step is to create a minimum case that reproduces the problem
you're seeing.
