[CMake] include restbed in my project

[J Decker]

So I have all these third party libraries I keep a copy of...
https://github.com/d3x0r/SACK/tree/master/src/contrib

So libressl for example, has cmakelists.txt

https://github.com/d3x0r/SACK/blob/master/CMakeLists.txt#L680
add_subdirectory( src/contrib/libressl/${LIBRESSL_VERSION} )

which I aliased a bit for upgrade/migration/regression...

I also link optionally to bullet...

IF( EXISTS ${BULLET_SOURCE}/CMakeLists.txt )
   # setup a bunch of options...
add_subdirectory( ${BULLET_SOURCE} bullet )


In the second case, bullet is outside my source tree, (next to it with
other top level projects), so I have to specify a name to be used in the
CMAKE_BINARY_DIR  (bullet) to use for temporary space to build...

and then just link like any other included target

target_link_libaraies( myThing bullet ssl tls crypto )


it's really not that hard, and if you don't understand add_subdirectory....
well... I can't imagine such a world it's so good for breaking up things
into related funcational groups...
