[Threads, Boost] Option to create IMPORTED targets with GLOBAL scope
Currently, when using find_package
to find Threads
or Boost
the created IMPORTED
targets (Threads::Threads
and Boost::...
) have local scope.
This merge-request provides a way to tell the FindThreads.cmake
and FindBoost.cmake
scripts to create their IMPORTED
targets with the additional GLOBAL
flag.
Finding Threads with global imported target:
set (THREADS_MAKE_GLOBAL_TARGET TRUE)
find_package(Threads)
# Creates target Threads::Threads with global scope.
Finding Boost.Thread with global imported target:
set (Boost_MAKE_GLOBAL_TARGETS TRUE)
find_package(Boost COMPONENT thread)
# Creates i.a. target Boost::thread with global scope and its dependency
# targets with global scope, too. (One of these is Threads::Threads.)
Note: This merge-request requires !1220 (merged) to be merged first.
