to the executable for its symbols are now linked using the import file.
The :command:`install(TARGETS)` command now installs the import file as
an ``ARCHIVE`` artifact.
* On AIX, runtime linking is no longer enabled by default. CMake provides
the linker enough information to resolve all symbols up front.
One may manually enable runtime linking for shared libraries and/or
loadable modules by adding ``-Wl,-G`` to their link flags
(e.g. in the :variable:`CMAKE_SHARED_LINKER_FLAGS` or
:variable:`CMAKE_MODULE_LINKER_FLAGS` variable).
One may manually enable runtime linking for executables by adding
``-Wl,-brtl`` to their link flags (e.g. in the
:variable:`CMAKE_EXE_LINKER_FLAGS` variable).
