-# Updated FindThreads.cmake that supports pthread-win32
-# Downloaded from http://www.vtk.org/Bug/bug_view_advanced_page.php?bug_id=6399
-
-# - 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
-#
-# If use of pthreads-win32 is desired, the following variables
-# can be set.
-#
-# THREADS_USE_PTHREADS_WIN32 -
-# Setting this to true searches for the pthreads-win32
-# port (since CMake 2.8.0)
-#
-# THREADS_PTHREADS_WIN32_EXCEPTION_SCHEME
-# C = no exceptions (default)
-# (NOTE: This is the default scheme on most POSIX thread
-# implementations and what you should probably be using)
-# CE = C++ Exception Handling
-# SE = Structure Exception Handling (MSVC only)
-# (NOTE: Changing this option from the default may affect
-# the portability of your application. See pthreads-win32
-# documentation for more details.)
-#
-#======================================================
-# Example usage where threading library
-# is provided by the system:
-#
-# find_package(Threads REQUIRED)
-# add_executable(foo foo.cc)
-# target_link_libraries(foo ${CMAKE_THREAD_LIBS_INIT})
-#
-# Example usage if pthreads-win32 is desired on Windows
-# or a system provided thread library:
-#
-# set(THREADS_USE_PTHREADS_WIN32 true)
-# find_package(Threads REQUIRED)
-# include_directories(${THREADS_PTHREADS_INCLUDE_DIR})
-#
-# add_executable(foo foo.cc)
-# target_link_libraries(foo ${CMAKE_THREAD_LIBS_INIT})
