* Defer check for sources within a target until generation.Deniz Bahadir2017-10-241-8/+0
| | | | | | | | | | | | | | | The `add_library` and `add_executable` commands can now be called with no source-files and won't generate a warning or error message, as long as source-files will be added later via the `target_sources` command. If during the generation step still no sources are associated with targets created by such calls a useful error message will be generated and generation fails. Targets of type `INTERFACE_LIBRARY`, `UTILITY` or `GLOBAL_TARGET` are excluded from this check because we do not need sources for these target types during generation. Fixes: #16872

* Simplify CMake per-source license noticesBrad King2016-09-271-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.

Use `clang-format` version 3.8. * If you reached this commit for a line in `git blame`, re-run the blame operation starting at the parent of this commit to see older history for the content. * See the parent commit for instructions to rebase a change across this style transition commit.
* Format include directive blocks and ordering with clang-formatBrad King2016-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Otherwise add_library(SomeImportedLib UNKNOWN IMPORTED) warns on platforms that do not support shared libraries. Reported-by: Kelly Thompson <kgt@lanl.gov>

* cmMakefile: make some methods take const std::string& instead of const char*Rolf Eike Beer2014-01-161-1/+1
| | | | | | | | Most callers already have a std::string, on which they called c_str() to pass it into these methods, which internally converted it back to std::string. Pass a std::string directly to these methods now, avoiding all these conversions. Those methods that only pass in a const char* will get the conversion to std::string now only once.

* Add the INTERFACE_LIBRARY target type.Stephen Kelly2013-10-071-2/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | This target type only contains INTERFACE_* properties, so it can be used as a structural node. The target-specific commands enforce that they may only be used with the INTERFACE keyword when used with INTERFACE_LIBRARY targets. The old-style target properties matching LINK_INTERFACE_LIBRARIES_<CONFIG> are always ignored for this target type. The name of the INTERFACE_LIBRARY must match a validity generator expression. The validity is similar to that of an ALIAS target, but with the additional restriction that it may not contain double colons. Double colons will carry the meaning of IMPORTED or ALIAS targets in CMake 2.8.13. An ALIAS target may be created for an INTERFACE library. At this point it can not be exported and does not appear in the buildsystem and project files are not created for them. That may be added as a feature in a later commit. The generators need some changes to handle the INTERFACE_LIBRARY targets returned by cmComputeLinkInterface::GetItems. The Ninja generator does not use that API, so it doesn't require changes related to that.
* Add the ALIAS target concept for libraries and executables.Stephen Kelly2013-08-021-0/+80
| | | | | | | | | | | | | | | | | * 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.
* add_library: Allow OBJECT library without dynamic linking (#13289)Brad King2012-06-111-7/+8
| | | | | | | When global property TARGET_SUPPORTS_SHARED_LIBS is FALSE we should still allow OBJECT libraries. This was an oversight in commit b87d7a60 (Add OBJECT_LIBRARY target type, 2012-03-12). While at it, fix the warning message to report context.
* Add OBJECT_LIBRARY target typeBrad King2012-03-131-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | This library type can compile sources to object files but does not link or archive them. It will be useful to reference from executable and normal library targets for direct inclusion of object files in them. Diagnose and reject the following as errors: * An OBJECT library may not be referenced in target_link_libraries. * An OBJECT library may contain only compiling sources and supporting headers and custom commands. Other source types that are not normally ignored are not allowed. * An OBJECT library may not have PRE_BUILD, PRE_LINK, or POST_BUILD commands. * An OBJECT library may not be installed, exported, or imported. Some of these cases may be supported in the future but are not for now. Teach the VS generator that OBJECT_LIBRARY targets are "linkable" just like STATIC_LIBRARY targets for the LinkLibraryDependencies behavior.
* Optionally allow IMPORTED targets to be globally visibleBrad King2012-01-251-1/+7
| | | | | | | | | | | | 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.

* Convert CMake to OSI-approved BSD LicenseBrad King2009-09-281-14/+9
| | | | | | | 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.
* ENH: Add UNKNOWN type for IMPORTED librariesBrad King2008-08-181-0/+16
| | | | | | | | | | | | | | | When creating an IMPORTED target for a library that has been found on disk, it may not be known whether the library is STATIC or SHARED. However, the library may still be linked using the file found from disk. Use of an IMPORTED target is still important to allow per-configuration files to be specified for the library. This change creates an UNKNOWN type for IMPORTED library targets. The IMPORTED_LOCATION property (and its per-config equivalents) specifies the location of the library. CMake makes no assumptions about the library that cannot be inferred from the file on disk. This will help projects and find-modules import targets found on disk or specified by the user.
