* The ALIAS name must match a validity regex.
* Executables and libraries may be aliased.
* An ALIAS acts immutable. It can not be used as the lhs
of target_link_libraries or other commands.
* An ALIAS can be used with add_custom_command, add_custom_target,
and add_test in the same way regular targets can.
* The target of an ALIAS can be retrieved with the ALIASED_TARGET
target property.
* An ALIAS does not appear in the generated buildsystem. It
is kept separate from cmMakefile::Targets for that reason.
* A target may have multiple aliases.
* An ALIAS target may not itself have an alias.
* An IMPORTED target may not have an alias.
* An ALIAS may not be exported or imported.
Consider the case motivating commit e01cce28 (Allow add_dependencies()
on imported targets, 2010-11-19). An imported target references a file
generated at build time by a custom target on which it depends. Had the
file been built directly using add_library or add_executable its target
name would have been visible globally. Therefore the imported target
representing the file should be globally visible also.
Teach the IMPORTED signature of add_(executable|library) to accept a new
"GLOBAL" option to make the imported target visible globally.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
- Error if imported target is involved in conflict
- Error for non-imported target conflict unless
CMAKE_BACKWARDS_COMPATIBILITY <= 2.4
- Include OUTPUT_NAME property in error message
- Update add_executable and add_library command documentation
- 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
