[Bug 1273331] [NEW] Wrong handling of pthread in FindBoost macro

[Arne Nordmann]

Public bug reported:

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).
I attached a very simple cmake script to reproduce the error.

I reported this issue upstream[1] in cmake, where I was told, that the
pthread handling is not done by cmake, but patched by Ubuntu.

This issue is still existing in quantal, but no longer in saucy.
