- Created cmExportFileGenerator hierarchy to implement export file generation - Installed exports use per-config import files loaded by a central one. - Include soname of shared libraries in import information - Renamed PREFIX to NAMESPACE in INSTALL(EXPORT) and EXPORT() commands - Move addition of CMAKE_INSTALL_PREFIX to destinations to install generators - Import files compute the installation prefix relative to their location when loaded - Add mapping of importer configurations to importee configurations - Rename IMPORT targets to IMPORTED targets to distinguish from windows import libraries - Scope IMPORTED targets within directories to isolate them - Place all properties created by import files in the IMPORTED namespace - Document INSTALL(EXPORT) and EXPORT() commands. - Document IMPORTED signature of add_executable and add_library - Enable finding of imported targets in cmComputeLinkDepends
