Add a CMake based buildsystem for the tests.

This commit adds a CMake based buildsystem for the tests,
it separated the subsurface sources in small libraries to
make testing easyer ( subsurface core, subsurface ui,
subsurface profile, etc. )

There's no test yet, this however produces a compiled
and executable binary *on linux*. This file shouldn't
be needed on any other platform as this is not the main
build system, but the test build system.
