* 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.
* find_*: Add debug logging infrastructureRobert Maynard2019-12-191-0/+9
| | | | | | | | | | | | Enable debug messages a new `--find-debug` command-line option or via the `CMAKE_FIND_DEBUG_MODE` variable. This work was started by Chris Wilson, continued by Ray Donnelly, and then refactored by Robert Maynard to collect information into a single message per find query.

* find_package: Use PackageName_ROOT variables as search prefixesBrad King2018-03-161-3/+0
| | | | | | | | | | | | | | | | | | | This feature was originally added by commit v3.9.0-rc1~71^2~2 (find_*: Add a new PackageRoot search path group, 2017-05-03) and documented by commit v3.9.0-rc1~71^2 (find_*: Add docs for PackageRoot search path group, 2017-05-03). However, we had to disable the feature and remove the documentation in commit v3.9.1~2^2 (find_*: Disable the PACKAGE_ROOT search path group for CMake 3.9, 2017-08-08) due to breaking projects that used `PackageName_ROOT` variables themselves. Add policy `CMP0074` to restore the `PackageName_ROOT` variable behavior in a compatible way. Also revise the stack of root paths to store the paths themselves rather than the package names. This way the policy can be considered at the `find_package` call site instead of individual `find_` calls inside a find module. Co-Author: Chuck Atkins <chuck.atkins@kitware.com> Issue: #17144
* Use C++11 override instead of CM_OVERRIDEBrad King2017-09-151-1/+1
| | | | | | | | 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.
* find_*: Disable the PACKAGE_ROOT search path group for CMake 3.9Brad King2017-08-081-0/+3
| | | | | | | | | | | | | | | | Disable the feature added by commit v3.9.0-rc1~71^2~2 (find_*: Add a new PackageRoot search path group, 2017-05-03) and remove documentation added by commit v3.9.0-rc1~71^2 (find_*: Add docs for PackageRoot search path group, 2017-05-03). Unfortunately the name `<pkg>_ROOT` may already be set by projects for their own incompatible purposes. Disable the behavior change for now to fix the regression for CMake 3.9. We can restore it later with a policy. In order to keep the implementation and tests working, add an undocumented variable we can use in the tests to enable the behavior before the policy is introduced. Fixes: #17144
* cmFindCommon: Drop unused FilterPaths methodBrad King2017-07-111-5/+0
| | | | | | The method has not been used since commit v3.2.0-rc1~400^2~1 (Encapsulate search path manipulation functions into a seperate class, 2014-10-15).
* find_*: Add a new PackageRoot search path groupChuck Atkins2017-05-161-0/+2
| | | | | | The new PackageRoot search path group allows the PackageName_ROOT cmake and environment variables to be used as search prefixes for all find_* commands called from within a find module

* 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.

* Revise C++ coding style using clang-formatKitware Robot2016-05-161-5/+16
| | | | | | | | | | | | | 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.
* 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.

* Use containers of labeled search paths instead of individual membersChuck Atkins2014-11-121-9/+41
| | | | | | | Manage classes of search paths in labeled containers. This removes the need to have a seperate member variable for each type of search path, but also allows path types to be grouped togethor in various different ways and manipulated as subsets of the full set of search paths.
* Encapsulate search path manipulation functions into a seperate class.Chuck Atkins2014-11-111-27/+18
| | | | | | The functions for adding the various different types of paths have been factored out into a new class, cmSearchPath. It is to be used as a helper container class for the various find_* commands.
* Refactor and seperate search path construction for find commandsChuck Atkins2014-11-111-10/+24
| | | | | | | Prior to this commit, the set of search paths to traverse for find commands was incrementally constructed. This change allows each group of paths, i.e. CMakeVariablePaths, UserHintsPaths, SystemEnvironmentPaths, etc. to be constructed and manipulated independently, and then all combined togethor.
* strings: Remove cmStdString referencesBen Boeckel2014-03-081-2/+2
| | | | | | | | | | | Casts from std::string -> cmStdString were high on the list of things taking up time. Avoid such implicit casts across function calls by just using std::string everywhere. The comment that the symbol name is too long is no longer relevant since modern debuggers alias the templates anyways and the size is a non-issue since the underlying methods are generated since it's inherited.
* stringapi: Use strings for variable namesBen Boeckel2014-03-081-1/+1
| | | | Variable names are always generated by CMake and should never be NULL.
* Drop builtin command documentationBrad King2013-10-161-6/+0
| | | | | Drop all GetTerseDocumentation and GetFullDocumentation methods from commands. The command documentation is now in Help/command/*.rst files.
* Refactor find_* command final path list computationBrad King2011-09-231-2/+2
| | | | | | | All find_* commands re-root the list of paths and then add trailing slashes. Factor this pair of calls out into a dedicated method. The new method would be the only caller to AddTrailingSlashes, so subsume that method into it.
* Speedup find_* commands (#11412)Brad King2010-11-121-0/+2
| | | | | | | Delay computation of the command documentation until it is needed. It is wasteful to do it in the constructor on every call. Inspired-By: Christian Ehrlicher <Ch.Ehrlicher@gmx.de>
* Teach find_* commands to ignore some pathsTodd Gamblin2010-08-131-0/+8
| | | | | | | | Add platform configuration variable CMAKE_SYSTEM_IGNORE_PATH and user configuration variable CMAKE_IGNORE_PATH. These specify a set of directories that will be ignored by all the find commands. Update FindPackageTest so that several cases will fail without a functioning CMAKE_IGNORE_PATH.

* 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 HINTS option to find_* commands.Brad King2008-06-091-1/+3
| | | | | | - Hints are searched after user locations but before system locations - The HINTS option should have paths provided by system introspection - The PATHS option should have paths that are hard-coded guesses
* ENH: In find_* implementation centralize addition of trailing slashesBrad King2008-06-091-0/+3
| | | | | | - Create cmFindCommon::AddTrailingSlashes - Use it in cmFindBase and cmFindPackageCommand - Remove duplication from other find commands
* ENH: Refactor cmFindCommon, cmFindBase, and cmFindPackageCommandBrad King2008-06-051-15/+9
| | | | | | | | | | | - Add each part of the search order in a separate method. - Collect added paths in an ivar in cmFindCommon. - Move user path storage up to cmFindCommon and share between cmFindBase and cmFindPackageCommand. - Expand user path registry values up in cmFindCommon - Enables 32-/64-bit registry view for find_package - Disables registry expansion for paths not specified with the PATHS argument, which is not expected.
* ENH: Major improvements to the FIND_PACKAGE command. See bug #3659.Brad King2008-01-171-0/+95
- Use CMAKE_PREFIX_PATH and CMAKE_SYSTEM_PREFIX_PATH among other means to locate package configuration files. - Create cmFindCommon as base for cmFindBase and cmFindPackageCommand - Move common functionality up to cmFindCommon - Improve documentation of FIND_* commands. - Fix FIND_* commands to not add framework/app paths in wrong place.
