# - 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?

# If use of pthreads-win32 is desired, the following variables

# can be set.
|

#
|

# THREADS_USE_PTHREADS_WIN32 -

# C = no exceptions (default)

# (NOTE: This is the default scheme on most POSIX thread

# CE = C++ Exception Handling

# SE = Structure Exception Handling (MSVC only)
