FindBoost.cmake blindly adds `${CMAKE_THREAD_LIBS_INIT}` to
`${Boost_LIBRARIES}` when the component `thread` is found.
On Debian buster the `FindThreads.cmake` sets that to `-pthread`.
This breaks a bunch of stuff becakse `-pthread` is a linker flag, not a
library.
There were earlier fixes for `-lpthread`.
This PR expands upon them.
First this PR modifies the fix from ros#998 to not add `-l` to any linker flag.
Second it adds to the fix in ros#975 to make sure `-pthread` is passed to
downstream users.
There's no standard cmake variable for linker flags, so this PR opts to
create an interface target with just the flag, and add that to
`${PROJECT_NAME}_LIBRARIES` instead.
Both this PR and ros-visualization/python_qt_binding#68 are required to strip or `qt_gui_cpp` will fail at link time.

When
${PROJECT_NAME}_LIBRARIEScontains an imported cmake target, this command will blindly add it to the Makefile with a-loption in front. This PR uses a catkin function to extract the library path from imported cmake targets before passing it to the command.
