Summary0014720: FindBoost handles pthread different on first and second run
DescriptionWhen 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 ReproduceExecute 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 InformationAn obvious workaround, calling the find boost macro twice in a cmake script, doesn't help.
TagsNo tags attached.

The FindBoost module has had a major overhaul since 2.8.7.

Please try with CMake 2.8.11 or higher, preferably the latest release.

When I run vanilla cmake 2.8.12.1 I get:
  -- Boost_LIBRARIES: /usr/lib/libboost_thread.so
both on the first and second run.

Debian/Ubuntu seem to patch their FindBoost.cmake to add pthread:

I tested in a Ubuntu saucy VM with cmake 2.8.11.2 (which comes with saucy). First and second run produce the same result, which is

 -- Boost_LIBRARIES: /usr/lib/x86_64-linux-gnu/libboost_thread.so;/usr/lib/x86_64-linux-gnu/libpthread.so

which is fine.
