Resource objects might be linked to plugins. Since some plugins may
be present in LINK_LIBRARIES as the complex genexes, need to collect
them explicitly and iterate over plugin targets to find resource object
libraries that need to be exposed to end-point target executable.

# In CMake versions earlier than CMake 3.18, a subdirectory scope id is appended to the
|
|
# target name if the target is referenced in a target_link_libraries command from a
|
|
# different directory scope than where the target was created.
|
|
# Strip it.
|
|
#
|
|
# For informational purposes, in CMake 3.18, the target name looks as follows:
|
|
# ::@(0x5604cb3f6b50);Threads::Threads;::@
|
|
# This case doesn't have to be stripped (at least for now), because when we iterate over
|
|
# link libraries, the tokens appear as separate target names.
|
|
#
|
|
# Example: Threads::Threads::@<0x5604cb3f6b50>
|
|
# Output: Threads::Threads
