# 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}) |
