conditional compiling of subdirs

[Amilcar do Carmo Lucas]

Hi,

If you have several binary targets on the top dir (some use some 
libraries, some use other, some use all , some use only one or two)
You can get the desired behavior by making one of the binary targets 
active and compiling the active target (only the libraries that that 
target depends upon are recompiled)
