At the end you can see a version which was working well
but we found it somewhat complicated with the paths.

Yes. we do that.

Yes. we have this.

Yes. But how do that program generate the libraries
when they are not build yet?

cmake can be used for different paths in a source tree.
Trying to create both apps both are trying to build both
libraries on different locations - cmake complains.
The command after here fails without handling to use
"link_directories" or "add_subdirectory" properly:
/tmp/obj> cmake /projects/apps
1) I can rebuild all
2) I can build a set of applications
3) I can build just one application
Independent on what scenario I use I want to ensure that
all dependencies are built and used.
