| # 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}" ) |
