# FindThreads module for locating threads implementation.
|
|
#
|
|
# The module defines the following variables:
|
|
#
|
|
# 'Threads_FOUND'
|
|
# Indicates if threads are supported.
|
|
#
|
|
# 'CMAKE_THREAD_LIBS_INIT'
|
|
# The threads library to use. Zephyr provides threads implementation and no
|
|
# special flags are needed, so this will be empty.
|
|
#
|
|
# 'CMAKE_USE_PTHREADS_INIT'
|
|
# Indicates if threads are pthread compatible.
|
|
#
|
|
# This module is compatible with FindThreads module from CMake.
|
|
# The original implementation tries to find threads library using various
|
|
# methods (e.g. checking if pthread library is present or compiling example
|
|
# program to check if the implementation is provided by libc), but it's not
|
|
# able to detect pthread implementation provided by Zephyr.
