# 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

The following import target is created

    Threads::Threads

For systems with multiple thread libraries, caller can set

    CMAKE_THREAD_PREFER_PTHREAD

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

    THREADS_PREFER_PTHREAD_FLAG

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.
