Do not use.
|
|
|
|
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.

CMAKE_EXPAND_IMPORTED_TARGETS() takes a list of libraries and replaces
|
|
all imported targets contained in this list with their actual file
|
|
paths of the referenced libraries on disk, including the libraries
|
|
from their link interfaces. If a CONFIGURATION is given, it uses the
|
|
respective configuration of the imported targets if it exists. If no
|
|
CONFIGURATION is given, it uses the first configuration from
|
|
${CMAKE_CONFIGURATION_TYPES} if set, otherwise ${CMAKE_BUILD_TYPE}.
