CMAKE_EXPAND_IMPORTED_TARGETS(<var> LIBRARIES lib1 lib2...libN
                              [CONFIGURATION <config>])

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}. This macro is used by all Check*.cmake files which use try_compile() or try_run() and support CMAKE_REQUIRED_LIBRARIES , so that these checks support imported targets in CMAKE_REQUIRED_LIBRARIES:

cmake_expand_imported_targets(expandedLibs
  LIBRARIES ${CMAKE_REQUIRED_LIBRARIES}
  CONFIGURATION "${CMAKE_TRY_COMPILE_CONFIGURATION}" )
