* cmExport*FileGenerator: support exporting C++ module propertiesBen Boeckel2022-07-061-0/+4
| | | | | C++ module properties will be generated at build time, so generate code that includes the files actually responsible for the information.
* exports: support `CXX_MODULES_DIRECTORY`Ben Boeckel2022-07-061-0/+12
| | | | | | | | | | | | This directory will be used to store build-discovered information about targets such as the modules provided by the files in the relevant `FILE_SET` types. A directory is used because basing the name on a `<FILE_NAME>-*.cmake` pattern makes it end up being globbed in the configuration-dependent information mechanism. Since old modules and targets may be around, unconditionally including them may refer to targets that do not actually exist.

* cmExportFileGenerator: Simplify collection of targets missing from export setBrad King2022-04-111-4/+2
| | | | | Store the list of missing target names in a member instead of threading an explicit reference to it through the call stack.

* Refactor export file generator intefaceEugene Shalygin2021-07-221-4/+4
| | | | | Replace cmTargetExport with const cmGeneratorTarget to allow recursive processing of exported targets and their link dependencies.
* Modernize: Use #pragma once in all header filesKitware Robot2020-09-031-4/+1
| | | | | | | | | | | | | | | | #pragma once is a widely supported compiler pragma, even though it is not part of the C++ standard. Many of the issues keeping #pragma once from being standardized (distributed filesystems, build farms, hard links, etc.) do not apply to CMake - it is easy to build CMake on a single machine. CMake also does not install any header files which can be consumed by other projects (though cmCPluginAPI.h has been deliberately omitted from this conversion in case anyone is still using it.) Finally, #pragma once has been required to build CMake since at least August 2017 (7f29bbe6 enabled server mode unconditionally, which had been using #pragma once since September 2016 (b13d3e0d)). The fact that we now require C++11 filters out old compilers, and it is unlikely that there is a compiler which supports C++11 but does not support #pragma once.
* Refactoring: use append functions from cmext/algorithmMarc Chevrier2019-12-171-2/+3

* Revise include order using clang-format-6.0Kitware Robot2019-10-011-4/+4
| | | | | Run the `clang-format.bash` script to update our C and C++ code to a new include order `.clang-format`. Use `clang-format` version 6.0.
* cmExportBuildFileGenerator: improve error messageBen Boeckel2019-06-271-3/+4
| | | | | | | | When an exported target depends on another exported target that is included in multiple build export sets, the error message was woefully unhelpful. Now, include information about what build exports the dependent target was included in with instructions for fixing the problem that are actually helpful.
* Use cmAppend to append ranges to std::vector instancesSebastian Holtermann2019-05-231-1/+2

* install,export: Maybe transform OBJECT libraries to INTERFACE librariesBrad King2018-02-281-0/+3
| | | | | | | | | | | 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.
* Use C++11 override instead of CM_OVERRIDEBrad King2017-09-151-4/+4
| | | | | | | | We now require C++11 support including `override`. Drop use of the old compatibility macro. Convert references as follows: git grep -l CM_OVERRIDE -- '*.h' '*.hxx' '*.cxx' | xargs sed -i 's/CM_OVERRIDE/override/g'
* IWYU: Mark cmConfigure.h with pragma: keepDaniel Pfeifer2017-08-261-1/+1
| | | | Also remove `#include "cmConfigure.h"` from most source files.
* Use quotes for non-system includesDaniel Pfeifer2017-04-111-1/+1
| | | | | | | | | | | | | Automate with: git grep -l '#include <cm_' -- Source \ | xargs sed -i 's/#include <\(cm_.*\)>/#include "\1"/g' git grep -l '#include <cmsys/' -- Source \ | xargs sed -i 's/#include <\(cmsys\/.*\)>/#include "\1"/g' git grep -l '#include <cm[A-Z]' -- Source \ | xargs sed -i 's/#include <\(cm[A-Z].*\)>/#include "\1"/g'
* 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.

| | | | | | | | | | | | | Run the `Utilities/Scripts/clang-format.bash` script to update all our C++ code to a new style defined by `.clang-format`. 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.
* Export: Port internal utility to cmGeneratorTarget.Stephen Kelly2015-10-181-4/+4

* Export: Port some API to cmGlobalGenerator.Stephen Kelly2015-10-181-2/+1

* cmMakefile: Store container of cmExportBuildFileGenerators.Stephen Kelly2015-10-141-6/+2
| | | | | | | | | Set a cmLocalGenerator on each instance at compute time. That will soon be needed to access cmGeneratorTarget instances. If a cmExportBuildFileGenerator is processed early during configure time as a result of CMP0024 it must be removed from the list to process later at generate time.

* cmMakefile: return a backtraceBen Boeckel2014-06-051-1/+1
| | | | | This allows backtraces to be fully controlled by the makefile rather than externally (and makes changing how they are manipulated easier).

* export: Implement EXPORT subcommand (#9822)Stephen Kelly2013-12-241-2/+5
| | | | | | Teach the export command to handle export sets defined by invocations of install(TARGETS ... EXPORT foo). This makes maintenance of targets exported to both the build tree and install tree trivial.
* export(): Handle multiple dependent export sets.Stephen Kelly2013-10-111-1/+5
| | | | | | | | | | | | The export-sets topic, merged in commit 49c7b649 (Merge topic 'export-sets', 2012-10-01) changed install(EXPORT) to allow exporting targets whose dependents are exported separately to different locations. Doing the same for export() was not possible because the export() command was executed at configure-time. Now that export() is also executed at generate-time, make it possible to export to multiple dependent export sets.
* export(): Process the export() command at generate time.Stephen Kelly2013-10-111-3/+9
| | | | | | | | | | | | Make the API for adding targets string based so that it can easily use cmGeneratorTarget. Teach the cmIncludeCommand to generate the exported file at configure-time instead if it is to be include()d. The RunCMake.ExportWithoutLanguage test now needs a dummy header.h file as expected error from export() is now reported after the missing file error.
* export(): Set a Makefile on the cmExportBuildFileGenerator.Stephen Kelly2013-10-101-5/+8
| | | | | | | | This is better than the cmCommand, because the lifetime of that is not as useful, and it is only used to report an error anyway. In the next commit, the cmExportBuildFileGenerator will outlive the cmCommand.
* OS X: Add support for @rpath in export files.Clinton Stimpson2013-06-031-0/+2
| | | | | Also expand the IMPORTED_SONAME property for targets to match the install_name.
* Move the exported check for dependencies of targetsStephen Kelly2013-01-151-1/+2
| | | | | Check only once, in the Config.cmake file, instead of once in each Config-<cfg>.cmake file.
* exports: move the handling of missing targets into subclassesAlex Neundorf2012-09-301-3/+8
| | | | | | | | | | Before, cmExportFileGenerator::ComplainAboutMissingTarget() was a virtual function which had to be implemented in the subclasses. It is not anymore. Instead, there is now a virtual function HandleMissingTargets(), which is implemented in the two subclasses. This makes e.g. dealing correctly with APPEND mode easier. Alex
* exports: accept a missing target if it is exported exactly onceAlex Neundorf2012-09-281-1/+2
| | | | | | | | | | | If a target is exported, and a library it depends on is not part of the same export set, before this patch cmake errored out. With this patch, it now checks whether the missing target is exported somewhere else exactly once, and accepts in this case (because then it can determine the namespace for the missing target and use this).

* 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: Pass dependent library search path to linker on some platforms.Brad King2008-02-011-1/+2
| | | | | | | | | | | | | | | | - 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
* ENH: Implemented link-interface specification feature.Brad King2008-01-301-0/+8
| | | | | | | | | | | | - 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.
