But that's one of the things that really bothers me. This is that redundancy
I was talking about earlier. If I do:

add_dependencies( C B )
target_link_libraries( C staticLibB )

It's a bit pointless. For example, CMake should be smart enough to know that
by adding a dependency to B, it should look at the library that it is
outputting (In this case, staticLibB.lib) and add that to an implicit call
to target_link_libraries(). I only want to use target_link_libraries() to
link against external third party libraries that aren't explicitly
represented as a project in my CMake build process.

If I decide to change the output name for the static library B outputs, I'm
forced to then revisit all of the target_link_libraries() calls and rename
staticLibB. This is a management issue (amongst other things).
