# FindThreads
# -----------
#
# This module determines the thread library of the system.
#
# The following variables are set
#
# ::
#
# CMAKE_THREAD_LIBS_INIT - the thread library
# CMAKE_USE_SPROC_INIT - are we using sproc?
# CMAKE_USE_WIN32_THREADS_INIT - using WIN32 threads?
# CMAKE_USE_PTHREADS_INIT - are we using pthreads
# CMAKE_HP_PTHREADS_INIT - are we using hp pthreads
#
# For systems with multiple thread libraries, caller can set
#
# ::
#
# CMAKE_THREAD_PREFER_PTHREAD
