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

The following import target is created


For systems with multiple thread libraries, caller can set


If the use of the -pthread compiler and linker flag is prefered then the caller can set


Please note that the compiler flag can only be used with the imported target. Use of both the imported target as well as this switch is highly recommended for new code.
