You may specify this variable and if set +# when FindBoost searches for the Boost threading library +# it will first try to match the threadapi you specify. +# For Example: libboost_thread_win32-mgw45-mt-1_43.a +# might be found if you specified "win32" here before +# falling back on libboost_thread-mgw45-mt-1_43.a. +# [Since CMake 2.8.3] +# +# Boost_REALPATH Resolves symbolic links for discovered boost libraries +# to assist with packaging.
