# - Work around improper pthread library specification by FindBoost

# FindBoost only adds pthreads to the libraries to link to on the first run

# of CMake and also does not do that via a path but as a base_library_name

# (i.e. pthread instead of /usr/lib/libpthread.a) which causes problems when

# linking statically

#

# Include this file after the FindBoost call that includes the thread component
