#.rst:
# CopyImportedTargetProperties
# --------------------------
#
# Copies the `INTERFACE*` and `IMPORTED*` properties from a target
# to another one.
# This function can be used to duplicate an `IMPORTED` or an `ALIAS` library
# with a different name since ``add_library(... ALIAS ...)`` does not work
# for those targets.
#
# ::
#
# copy_imported_target_properties(<source-target> <destination-target>)
#
# The function copies all the `INTERFACE*` and `IMPORTED*` target
# properties from `<source-target>` to `<destination-target>`.
#
# The function uses the `IMPORTED_CONFIGURATIONS` property to determine
# which configuration-dependent properties should be copied
# (`IMPORTED_LOCATION_<CONFIG>`, etc...)
#
# Example:
#
# Internally the CMake project of ZLIB builds the ``zlib`` and
# ``zlibstatic`` targets which can be exported in the ``ZLIB::`` namespace
# with the ``install(EXPORT ...)`` command.
#
# The config-module will then create the import libraries ``ZLIB::zlib`` and
# ``ZLIB::zlibstatic``. To use ``ZLIB::zlibstatic`` under the standard
# ``ZLIB::ZLIB`` name we need to create the ``ZLIB::ZLIB`` imported library
# and copy the appropriate properties:
#
# add_library(ZLIB::ZLIB STATIC IMPORTED)
# copy_imported_target_properties(ZLIB::zlibstatic ZLIB::ZLIB)
#
function(copy_imported_target_properties src_target dest_target)
