Summary:                    FindBoost handles pthread different on first and
second run
Description: 
When calling the macro find_package(Boost thread), I get different results for
${Boost_LIBRARIES} the first and the second time I execute cmake.

First time, ${Boost_LIBRARIES} contains
'/usr/lib/libboost_thread-mt.so;pthread', the second time, ${Boost_LIBRARIES}
just contains '/usr/lib/libboost_thread-mt.so' (without pthread).

Steps to Reproduce: 
Execute the following cmake script twice (also attached):

> project("Test FindBoost")
> cmake_minimum_required(VERSION 2.8)
> find_package(Boost REQUIRED thread)
> message(STATUS "Boost_LIBRARIES: ${Boost_LIBRARIES}")

Reproduced on several Ubuntu precise and quantal machines.

Additional Information: 
An obvious workaround, calling the find boost macro twice in a cmake script,
doesn't help.
