Summary

0014986: FindBoost with component thread does not properly link with boost_system

Description

When just finding the thread component of Boost it appears that one also has to link with boost_system. From the Boost documentation it looks like this change was introduced with version 1.52 (see http://www.boost.org/doc/libs/1_52_0/doc/html/thread/build.html [^]).

Steps To Reproduce

FIND_PACKAGE(Boost COMPONENTS thread)
target_link_libraries(my_target ${Boost_LIBRARIES})

Resulting in a linker error like the following:
/usr/bin/ld: CMakeFiles/<something>.dir/<something>.o: undefined reference to symbol '_ZN5boost6system15system_categoryEv'
//usr/lib/x86_64-linux-gnu/libboost_system.so.1.54.0: error adding symbols: DSO missing from command line

Linking with boost_system (i.e. -lboost_system or target_link_libraries(my_target boost_system)) solves the issue, but it should be done automatically when finding the thread component of Boost.

Notes
(0036234) Brad King (manager) 2014-06-23 11:28	AFAICT, FindBoost does not encode any of the Boost library dependencies nor does the documentation claim so.
