We create target property "LINK_INTERFACE_MULTIPLICITY" and a per-config
version "LINK_INTERFACE_MULTIPLICITY_<CONFIG>". It sets the number of
times a linker should scan through a mutually dependent group of static
libraries. The largest value of this property on any target in the
group is used. This will help projects link even for extreme cases of
cyclic inter-target dependencies.
Now that languages are part of the link interface of a target we need to
export/import the information. A new IMPORTED_LINK_INTERFACE_LANGUAGES
property and per-config IMPORTED_LINK_INTERFACE_LANGUAGES_<CONFIG>
property specify the information for imported targets. The export() and
install(EXPORT) commands automatically set the properties.
When LINK_INTERFACE_LIBRARIES is not set we use the link implementation
to implicitly define the link interface. These changes centralize the
decision so that all linkable targets internally have a link interface.
- Move runtime path ordering out of cmComputeLinkInformation
into its own class cmOrderRuntimeDirectories.
- Create an instance of cmOrderRuntimeDirectories for runtime
path ordering and another instance for dependent library
path ordering.
- Replace CMAKE_DEPENDENT_SHARED_LIBRARY_MODE with explicit
CMAKE_LINK_DEPENDENT_LIBRARY_FILES boolean.
- Create CMAKE_LINK_DEPENDENT_LIBRARY_DIRS boolean.
- Create variables to specify -rpath-link flags:
CMAKE_SHARED_LIBRARY_RPATH_LINK_<LANG>_FLAG
CMAKE_EXECUTABLE_RPATH_LINK_<LANG>_FLAG
- Enable -rpath-link flag on Linux and QNX.
- Documentation and error message updates
- Split IMPORTED_LINK_LIBRARIES into two parts:
IMPORTED_LINK_INTERFACE_LIBRARIES
IMPORTED_LINK_DEPENDENT_LIBRARIES
- Add CMAKE_DEPENDENT_SHARED_LIBRARY_MODE to select behavior
- Set mode to LINK for Darwin (fixes universal binary problem)
- Update ExportImport test to account for changes
- Shared libs and executables with exports may now have
explicit transitive link dependencies specified
- Created LINK_INTERFACE_LIBRARIES and related properties
- Exported targets get the interface libraries as their
IMPORTED_LINK_LIBRARIES property.
- The export() and install(EXPORT) commands now give
an error when a linked target is not included since
the user can change the interface libraries instead
of adding the target.
- Imported bundles have the MACOSX_BUNDLE property set
- Added cmTarget::IsAppBundleOnApple method to simplify checks
- Document BUNDLE keyword in INSTALL command
- Updated IMPORTED_LOCATION property documentation for bundles
- Updated ExportImport test to test bundles
- Imported frameworks have the FRAMEWORK property set
- Added cmTarget::IsFrameworkOnApple method to simplify checks
- Also remove separate IMPORTED_ENABLE_EXPORTS property and just use ENABLE_EXPORTS since, like FRAMEWORK, it just represents the target type.
- Document FRAMEWORK keyword in INSTALL command.
- Updated IMPORTED_LOCATION property documentation for Frameworks
- 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
