[CMake] Build dependent targets

[Ellon Paiva]

Hi,

I was wondering: is there any way to compile all targets that depend on 
a given target ? (i.e. the "dependent targets", if my English does not 
fail).

In my particular case, I have a huge project that contains many libs and 
executables, and I would like to check that the targets that depend on 
the library I'm working on do not break with my modifications, but I 
wouldn't like to compile the whole project every time since not all 
targets depends on my lib.

Best,

Ellon
