* Add usage requirements to update direct link dependenciesBrad King2022-01-293-2/+34
| | | | | | | | | | | | | | | | | Link line construction starts with `LINK_LIBRARIES` and appends dependencies from the transitive closure of `INTERFACE_LINK_LIBRARIES`. Only the entries of `LINK_LIBRARIES` are considered direct link dependencies. In some advanced use cases, particularly involving static libraries and static plugins, usage requirements need to update the list of direct link dependencies. This may mean adding new items, removing existing items, or both. Add target properties to encode these usage requirements: * INTERFACE_LINK_LIBRARIES_DIRECT * INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE Fixes: #22496
* LCC: Add policy CMP0129 regarding interpreting LCC as GNUmakise-homura2021-10-212-0/+6
| | | | | | | | | | Due to MCST LCC compiler identification is now changed to LCC, there should be a way for old projects to still identify it as GNU, as it was before. This commits adds the policy: CMP0129: Compiler id for MCST LCC compilers is now LCC, not GNU. This policy controls such a behavior. OLD behaivior is to treat LCC as GNU, NEW is to treat is as LCC.

| * LCC: Add dedicated support for MCST LCC compilermakise-homura2021-10-152-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Divert LCC compiler as a new one, instead of treating it as GNU. Since old times, Elbrus C/C++/Fortran Compiler (LCC) by MCST has been passing checks for GNU compilers, so it has been identified as GNU. Now, with intent of seriously upstreaming its support, it has been added as a separate LCC compiler, and its version displays not a supported GCC version, but LCC version itself (e.g. LCC 1.25.19 instead of GNU 7.3.0). This commit adds its support for detection, and also converts basically every check like 'is this compiler GNU?' to 'is this compiler GNU or LCC?'. The only places where this check is untouched, is where it regards other platforms where LCC is unavailable (primarily non-Linux), and where it REALLY differs from GNU compiler. Note: this transition may break software that are already ported to Elbrus, but hardly relies that LCC will be detected as GNU; still such software is not known.
* | export: Propagate IMPORTED_NO_SYSTEM target property to consumersBrad King2021-10-155-0/+31
|/ | | | | | | | | Enabling `IMPORTED_NO_SYSTEM` on a target built within the project has no effect on the build system, but it is still a useful way to set the property on imported targets generated by `install(EXPORT)` and `export()`. Issue: #17364

* Add INTERFACE libraries to generated buildsystem if they have SOURCESBrad King2020-08-074-3/+41
| | | | | | | | | | | | | | | | | | | | | | | | INTERFACE libraries were created with the intention of collecting usage requirements for use by other targets via `target_link_libraries`. Therefore they were not allowed to have SOURCES and were not included in the generated buildsystem. In practice, this has become limiting: * Header-only libraries do have sources, they just do not compile. Developers should be able to edit those sources (the header files) in their IDE. * Header-only libraries may need to generate some of their header files via custom commands. Some projects work around these limitations by pairing each interface library with an `add_custom_target` that makes the header files and custom commands appear in the generated buildsystem and in IDEs. Lift such limitations by allowing INTERFACE libraries to have SOURCES. For those with sources, add a corresponding build target to the generated buildsystem. Fixes: #19145
* target_link_libraries: Fix out-of-dir linking of a list of targetsBrad King2020-01-161-1/+1
| | | | | | | | | | | | | | In a case like target_link_libraries(targetInOtherDir PUBLIC "$<1:a;b>") then all entries in the list need to be looked up in the caller's scope. Previously our `::@(directory-id)` suffix would apply only to the last entry. Instead surround the entire entry by a pair `::@(directory-id);...;::@` so that the `::@` syntax can encode a directory lookup scope change evaluated as the list is processed. Fixes: #20204
* Tests: Enable CMP0022 in ExportImport out-of-dir linking caseBrad King2020-01-141-0/+1
| | | | | | Since out-of-dir linking is enabled by CMP0079, which is newer than CMP0022, it is likely that both will be set in practice when out-of-dir linking is used.
* Add set_property option: DEPRECATIONJoseph Snyder2020-01-022-0/+12
| | | | | | | | | | | | Add a new property flag for a target which contains a message regarding deprecation status. Add a warning at "Generate" time if a linked target is marked as deprecated. Expand ExportImport test to ensure that new property is being set and passed correctly. Ensure that the message is shown during the "Generate" step run of the ExportImport test.

If the value starts in `${_IMPORT_PREFIX}` (which comes from `$<INSTALL_PREFIX>`) then it is an absolute path. Fixes: #19791

* LINK_DIRECTORIES: Add new properties and commandsMarc Chevrier2018-09-252-0/+17
| | | | | | | | | | | | These new capabilities enable to manage link directories Two new properties: * target properties: LINK_DIRECTORIES and INTERFACE_LINK_DIRECTORIES One new command * target_link_directories(): to populate target properties Fixes: #17215
* target_link_libraries: Allow use with targets in other directoriesBrad King2018-09-127-0/+66
| | | | | | | | | | | | | | | | | | | | | Previously the command did not allow naming targets on the LHS that were not created in the calling directory. Lift this restriction to enable more flexible use by projects. Targets named on the RHS will need to be looked up during generation in the scope of the call site rather than the scope of the LHS target. Introduce an internal syntax in `[INTERFACE_]LINK_LIBRARIES` properties to specify target names that need to be looked up in a directory other than that containing the target on which the property is set. Add minimal documentation of the syntax to help users that encounter it. Unfortunately CMake previously did allow such calls in the case that only `INTERFACE` libraries are specified, but those libraries would be looked up in the target's directory rather than the caller's. Add policy `CMP0079` to enable the new behavior with new lookup scope in a compatible way. Fixes: #17943
* Tests: Add test for $<0:...> in ExportImportKyle Edwards2018-07-171-3/+3

* Export: allow exporting of additional propertiesWouter Klouwen2018-03-162-0/+22
| | | | | | | | | This change introduces an additional property that may be set on a target to allow additional properties to be exported. Normally only a limited number of properties are exported. Additional properties may be exported by simply setting the `EXPORT_PROPERTIES` property on a target that is exported.
* Tests: Add cases for usage requirements of linked object libsBrad King2018-03-018-19/+91
| | | | | | | Add tests to cover transitive usage requirements on installation and export of targets that link to object libraries. Issue: #14778
* install,export: Maybe transform OBJECT libraries to INTERFACE librariesBrad King2018-02-283-5/+31
| | | | | | | | | | | Teach the `install` and `export` commands to support installing and exporting `OBJECT` libraries without their object files. Transform them to `INTERFACE` libraries in such cases. For `install(TARGETS)`, activate this when no destination for the object files is specified. For `export`, activate this only under Xcode with multiple architectures when we have no well-defined object file locations to give to clients.

* Format include directive blocks and ordering with clang-formatBrad King2016-04-292-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sort include directives within each block (separated by a blank line) in lexicographic order (except to prioritize `sys/types.h` first). First run `clang-format` with the config file: --- SortIncludes: false ... Commit the result temporarily. Then run `clang-format` again with: --- SortIncludes: true IncludeCategories: - Regex: 'sys/types.h' Priority: -1 ... Commit the result temporarily. Start a new branch and cherry-pick the second commit. Manually resolve conflicts to preserve indentation of re-ordered includes. This cleans up the include ordering without changing any other style. Use the following command to run `clang-format`: $ git ls-files -z -- \ '*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' | egrep -z -v '(Lexer|Parser|ParserHelper)\.' | egrep -z -v '^Source/cm_sha2' | egrep -z -v '^Source/(kwsys|CursesDialog/form)/' | egrep -z -v '^Utilities/(KW|cm).*/' | egrep -z -v '^Tests/Module/GenerateExportHeader' | egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' | xargs -0 clang-format -i This selects source files that do not come from a third-party.

* Fix export of STATIC library PRIVATE dependencies with CMP0022 NEWBrad King2016-01-153-1/+13
| | | | | | | | | | | | | | The target_link_libraries command records the PRIVATE dependencies of a STATIC library in INTERFACE_LINK_LIBRARIES as "$<LINK_ONLY:dep>". This hides the target name from export namespacing logic inside a generator expression. When user-written generator expressions reference a target name they must put it inside a "$<TARGET_NAME:dep>" expression to allow the export logic to rename the target. In the case that the private dependency is not already a generator expression, target_link_libraries must use "$<LINK_ONLY:$<TARGET_NAME:dep>>" to allow the export logic to rename the target.
