TCP and CMake

[AndreasAakesson]

Small error in TCP.

Also made it possible to easier include IncludeOS libs.

# THIRD PARTY LIBRARIES:

set(LIBRARIES
  "libmana.a"
  )

This will first search for libmana.a locally. If not found, it tries the includeos/lib directory. If nothing there it fails as usual.
