Either you're wrong or your posted sample is :)

Note that this line above creates a target called 'b' which will build a
library called "b.lib".

This tries to link the target e against a target named 'b.b'. But this
target doesn't exist. Hence cmake assumes this is the name of a library
provided outside of the project and append ".lib" to it.

If you want to create a library called 'b.b' you should pass that as
target name to add_library. At least on unix this creates a correct
dependency.
