# This module was once needed to expand imported targets to the underlying
|
||||
# libraries they reference on disk for use with the :command:`try_compile`
|
||||
# and :command:`try_run` commands. These commands now support imported
|
||||
# libraries in their ``LINK_LIBRARIES`` options (since CMake 2.8.11
|
||||
# for :command:`try_compile` and since CMake 3.2 for :command:`try_run`).
|
||||
#
|
||||
# This module does not support the policy :policy:`CMP0022` ``NEW``
|
||||
# behavior or use of the :prop_tgt:`INTERFACE_LINK_LIBRARIES` property
|
||||
# because :manual:`generator expressions <cmake-generator-expressions(7)>`
|
||||
# cannot be evaluated during configuration.
