Package: cmake
Version: 2.8.0-5
Severity: minor
When using
find_package(Boost COMPONENTS thread REQUIRED)
-lpthread is not added to the link command, causing the link to fail if
binutils-gold (which has --no-add-needed behavior as default) is used.
More informations can be found at
http://wiki.debian.org/qa.debian.org/FTBFS#A2009-11-02Packagesfailingbecausebinutils-gold.2BAC8-indirectlinking
See attached testcase.
Thanks,
Ludovico
