[CMake] static linking on Ubuntu

[hemant at mnkcg.com]

Hi folks,

 

The P4 programming language has a compiler called p4c with a variant in
p4c-xp.  This compiler executable is built on Ubuntu 16.04.   p4c-xp uses
cmake.  As one can see, there are several shared libs used by p4c-xp.  Each
shared lib may call other shared libs.  I could use some help with cmake.  I
have used some cmake help for creating a single static lib but the steps did
not help on Ubuntu.  Further, I would like cmake to automatically detect
other shared lib dependencies and build a statically linked executable.
