Hi,

I read the documentation about Native Genode port of a library from the
gnode website[1]. It looks very easy to "create a port" of a library for
genode. I started to port a library and I have realized what is meant 
by Chapter "Creating the build Makefile".
This Chapter says, that I should create a build (Makefile) for
the third party source code ? 

I was expected that the port mechanism from genode will execute the 
configure script (Cross compiling) of the third party just as the 
"source based" Linux/UNIX (FreeBSD/Arch Linux) systems does.

I investigate for example how libssh is ported and I see that in
genode/repos/libports/lib/mk/libssh.mk every source file are added.
For such a small lib it is easy but for a bigger lib like Qt5, I see there
are helper scripts to generate the port mk for genode ?

I didn't use "Makefiles" in my projects. I'm a cmake user :-).
So my knowledge about Makefiles are very poor. Maybe I missed something.

My question: 
It is not possible to execute the "third party build system" to 
cross compile it for genode?

My port idea/work:
I didn't see any information about boost on the 
"Future Challenges of the Genode project"[2] or 
"Genode Porting Wishlist"[3] site, so I try to port boost to genode. 
Maybe somebody is also working on this?

Cheers
Jörg
