* Find*: Update *_FOUND variablesPeter Kokot2025-09-231-3/+3
| | | | | | | | | | | | | | | | | | | | | This marks all `<PACKAGENAME>_FOUND` result variables as deprecated where possible (for `<PackageName>` find modules) to make it clearer which variable to use. In CMake 3.3, the FindPackageHandleStandardArgs module was refactored to set both `<PackageName>_FOUND` and uppercase `<PACKAGENAME>_FOUND` result variables to the same values. Before that, the FOUND_VAR argument could be used to set the result variable. * FindMatlab: Uppercased MATLAB_FOUND is not mentioned as it was never documented. * Documentation for FindPythonInterp and FindPythonLibs modules synced accordingly to their deprecation (3.12 instead of 4.2). * OPENGL_FOUND: deprecation version synced with other find modules. * DevIL_FOUND was introduced in CMake 3.8. The uppercased variant not mentioned as it was previously never documented. Fixes: #27242
* FindPkgConfig: Deprecate PKG_CONFIG_FOUNDPeter Kokot2025-08-201-1/+1
| | | | | | | | | | Since most of the find modules use the `<PackageName>_FOUND` result variables, this now also syncs it for the FindPkgConfig module. The `PkgConfig_FOUND` result variable is available since CMake 3.3 and contains the same value. There is also `PKGCONFIG_FOUND` result variable automatically set with the same value but for simplicity isn't documented. The uppercased `<PACKAGENAME>_FOUND` result variables set by find modules are also considered legacy variables.
* Find*: Add intro code blocksPeter Kokot2025-08-041-1/+5
| | | | | | | | | | | - Added intro code blocks showing how to use find modules. - Synced modules documentation. - Extended few examples to make the intro code blocks fit into the modules descriptions. - Synced some RST formatting, variables descriptions and positions. - Removed few redundant internal comments. Issue: #26555
* FindCURL: Fix hardcoded outdated protocols and featuresPeter Kokot2025-04-161-17/+13
| | | | | | | | | | | | | | | | | This removes the hardcoded known protocols and features and only checks whether the specified component(s) by the `find_package(COMPONENT|OPTIONAL_COMPONENT <components>...)` call are found and listed by either the pkg-config or the curl-config tool. When curl is found via its CMake package configuration file, this issue wasn't relevant. Additionally, this also removes two internal FindCURL module variables `CURL_KNOWN_PROTOCOLS` and `CURL_KNOWN_FEATURES`. Redundant fatal error thrown is also removed as this is handled by the `find_package_handle_standard_args()`. Fixes #26866
* FindCURL: Update documentationPeter Kokot2025-04-131-35/+112
| | | | | | | | | | | | - Module documentation synced with other similar find modules. - Added examples section. - Joined all hints variables in a single section. - Added deprecated variables section. - Described the "module mode" and "config mode" when searching for CURL separately in the module introduction, and added notes to some result variables. Fixes #24580

* Modules/Find*: Include FindPackageHandleStandardArgs normallyBrad King2025-01-301-1/+1
| | | | | | | Since commit d74210a8bd (CMP0017: Remove support for OLD behavior, 2024-11-17) we can rely on CMP0017's NEW behavior unconditionally. Calling `include(FindPackageHandleStandardArgs)` in a builtin module will always get the builtin `FindPackageHandleStandardArgs`.
* FindCURL: Add CURL_VERSION variable to match upstream cmake packageBrad King2025-01-281-2/+10
| | | | | | | | | | | | `find_package(CURL CONFIG)` provides `CURL_VERSION` from the upstream cmake package version file. Upstream curl commit `699ac9430c` (cmake: publish/check supported protocols/features via `CURLConfig.cmake`, 2024-12-29) extends the upstream cmake package to provide our old `CURL_VERSION_STRING`. Provide both names from CMake's own module to aid transition. Fixes: #26634
* FindCURL: Add more target properties from pkg-configTobias Mayer2024-10-141-3/+18
| | | | | | | | | In case libcurl was found via pkg-config, the properties `INTERFACE_LINK_LIBRARIES`, `INTERFACE_LINK_OPTINS`, and `INTERFACE_COMPILE_OPTINS` can be populated from the `PC_CURL_*` variables if available. Fixes: #26365

* FindCURL: Fix parsing protocols/features from pkg-config outputlingbin2023-12-191-2/+4
| | | | | | Previously `find_package(CURL COMPONENTS HTTP)` failed because the `CURL_SUPPORTED_PROTOCOLS` variable returned by pkg-config is a command-line fragment, but we need a semicolon-separated list.
* FindCURL: add a CURL_USE_STATIC_LIBS hintEven Rouault2023-06-221-0/+23
| | | | | | | The effect of that hint is to set a CURL_STATICLIB compile definition, and to auxiliary system windows libraries for MSVC builds. GDAL-Issue: https://github.com/OSGeo/gdal/issues/7955
* FindCURL: Fix version string in case of multiple curl installationsGeorg Lutz2022-07-271-2/+1
| | | | | | | | | | | | | | On systems where there are two versions of libcurl installed CURL_VERSION_STRING is always set to the version found by the `pkg_check_modules(PC_CURL QUIET libcurl)`. But CURL_VERSION_STRING should match the libs and include paths found by `find_path` and `find_library` (more specifically the path where the header is found, because that where the version is parsed from. So make sure that the version is always parsed from the header file, use the output of pkg_check_modules only as HINT for find_path / find_library.
* FindCURL: Set CURL_VERSION_STRING when curl is found as a packagemakise-homura2022-06-281-0/+2
| | | | | | | FindCURL, when found as `curl-config.cmake`, will fill `CURL_VERSION` instead of `CURL_VERSION_STRING` variable. It may break some cases when user is relying on correct value of the latter variable, and as an example, already breaks `CMakeOnly.AllFindModules` test.

| * FindCURL: Fix list index check after searchMike Gelfand2020-07-281-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix logic added by commit fc5afbe970 (FindCURL: support COMPONENTS to check features, 2018-11-28, v3.14.0-rc1~287^2~2). When searching for particular components and `curl-config` reports one of the components being searched for first in the list, `find_package` fails. This is due to the check that treats non-zero index in the list as success and zero index as failure, while documentation on `list(FIND)` states that failure to find an element results in return value of -1 (not 0). I'm hitting this when building cURL with support for HTTP and HTTPS protocols only, and then trying to `find_package(CURL COMPONENTS HTTP HTTPS)`. I'm using `if(NOT x EQUAL -1)` check form as it appears to be the most used throughout the modules. While fixing this issue I've looked through all the uses of `list(FIND)` in other modules but wasn't able to find improper use except here.

| | | | | | | | | | | Upstream CURL provides imported target `CURL::libcurl`. Rename the target added by `FindCURL` to match. We don't need compatibility with the old name because it has never been in a CMake release (except a 3.12 release candidate).

* Simplify CMake per-source license noticesBrad King2016-09-271-14/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Remove CMake-language block-end command argumentsKitware Robot2012-08-131-2/+2
| | | | | | | | | | | | | | | | | Ancient versions of CMake required else(), endif(), and similar block termination commands to have arguments matching the command starting the block.

| | | | | | | | | | | | | | | | | Ancient CMake versions required upper-case commands. Later command names became case-insensitive. Now the preferred style is lower-case.

* Modules: Include builtin FindPackageHandleStandardArgs directlyBrad King2011-01-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FindPackageHandleStandardArgs module was originally created outside of CMake. It was added for CMake 2.6.0 by commit e118a627 (add a macro FIND_PACKAGE_HANDLE_STANDARD_ARGS..., 2007-07-18). However, it also proliferated into a number of other projects that at the time required only CMake 2.4 and thus could not depend on CMake to provide the module. CMake's own find modules started using the module in commit b5f656e0 (use the new FIND_PACKAGE_HANDLE_STANDARD_ARGS in some of the FindXXX modules..., 2007-07-18). Then commit d358cf5c (add 2nd, more powerful mode to find_package_handle_standard_args, 2010-07-29) added a new feature to the interface of the module that was fully optional and backward compatible with all existing users of the module. Later commit 5f183caa (FindZLIB: use the FPHSA version mode, 2010-08-04) and others shortly thereafter started using the new interface in CMake's own find modules. This change was also backward compatible because it was only an implementation detail within each module. Unforutnately these changes introduced a problem for projects that still have an old copy of FindPackageHandleStandardArgs in CMAKE_MODULE_PATH. When any such project uses one of CMake's builtin find modules the line include(FindPackageHandleStandardArgs) loads the copy from the project which does not have the new interface! Then the including find module tries to use the new interface with the old module and fails. Whether this breakage can be considered a backward incompatible change in CMake is debatable. The situation is analagous to copying a standard library header from one version of a compiler into a project and then observing problems when the next version of the compiler reports errors in its other headers that depend on its new version of the original header. Nevertheless it is a change to CMake that causes problems for projects that worked with previous versions. This problem was discovered during the 2.8.3 release candidate cycle. It is an instance of a more general problem with projects that provide their own versions of CMake modules when other CMake modules depend on them. At the time we resolved this instance of the problem with commit b0118402 (Use absolute path to FindPackageHandleStandardArgs.cmake everywhere, 2010-09-28) for the 2.8.3 release. In order to address the more general problem we introduced policy CMP0017 in commit db44848f (Prefer files from CMAKE_ROOT when including from CMAKE_ROOT, 2010-11-17). That change was followed by commit ce28737c (Remove usage of CMAKE_CURRENT_LIST_DIR now that we have CMP0017, 2010-12-20) which reverted the original workaround in favor of using the policy. However, existing project releases do not set the policy behavior to NEW and therefore still exhibit the problem. We introduced in commit a364daf1 (Allow users to specify defaults for unset policies, 2011-01-03) an option for users to build existing projects by adding -DCMAKE_POLICY_DEFAULT_CMP0017=NEW to the command line. Unfortunately this solution still does not allow such projects to build out of the box, and there is no good way to suggest the use of the new option. The only remaining solution to keep existing projects that exhibit this problem building is to restore the change originally made in commit b0118402 (Use absolute path to FindPackageHandleStandardArgs.cmake everywhere, 2010-09-28). This also avoids policy CMP0017 warnings for this particular instance of the problem the policy addresses.
