* FindPkgConfig: Fix preservation of ENV{PKG_CONFIG_ALLOW_SYSTEM_LIBS}Brad King2022-05-121-1/+3
| | | | | | | | | | | | Fix the ENV save/restore added by commit 36979f5b43 (FindPkgConfig: Tolerate PKG_CONFIG_SYSTEM_LIBRARY_PATH in environment, 2021-07-13, v3.22.0-rc1~407^2) to unset the variable if it was originally not set. While at it, clarify the value to which we temporarily set it. The `pkg-config` and `pkgconf` tools only check that the variable is set, and do not care about the value. Set it to a more true-looking value. Issue: #22148
* FindPkgConfig: Restore finding pkg-config before pkgconfBrad King2021-12-021-1/+1
| | | | | | | | | | | Since commit 94a84dc0af (FindPkgConfig: add pkgconf to the search list., 2021-07-02, v3.22.0-rc1~468^2), `pkgconf` is preferred over `pkg-config` if they appear in the same directory. In some environments, `pkg-config` may be a wrapper that adds semantics beyond either `pkgconf` or the normal `pkg-config`. Prefer `pkg-config` over `pkgconf` in order to preserve the prior behavior in such environments. Fixes: #22976

| | | | | | | | | | | | | | | | Tell `pkg-config --libs` not to filter out `-L` flags for entries of `PKG_CONFIG_SYSTEM_LIBRARY_PATH` (and `LIBRARY_PATH` for `pkgconf`). We should always search everywhere the `.pc` file expects. Fixes: #22148

* | FindPkgConfig: split args if loaded from environmentChristopher Degawa2021-06-181-5/+34
|/ | | | | | | | | | | | | | | It's common for some people to use the PKG_CONFIG environment variable to not only load a custom pkg-config/pkgconf but also to load some default arguments such as `--static` or `--keep-system-libs` which often worked since shell scripts would call `$PKG_CONFIG --libs pkg` without quotes, but this breaks FindPkgConfig since it uses the full string as `argv[0]` and might try looking for a binary called `pkgconf --static`, instead of looking for `pkgconf` and adding `--static` as the `argv[1]` Additionally adds RunCMake.FindPkgConfig ARGN test case Fixes: #22305 Signed-off-by: Christopher Degawa <ccom@randomderp.com>

| | | | | | | | | | | | | | | | | | | | Since commit ab8bd48352 (FindPkgConfig: Search for pkg-config.bat file on a Windows host, 2020-09-25, v3.19.0-rc1~98^2) we prefer `pkg-config.bat` over `pkg-config` regardless of the order they appear in the `PATH`. Tell `find_program` to consider all names in each directory so that the first one in `PATH` of any name wins. Issue: #21239

* FindPkgConfig: Search for pkg-config.bat file on a Windows hostAlexandru Croitor2020-09-251-1/+7
| | | | | | | | | | | | | | | | The strawberry perl distribution ships a pkg-config file and a pkg-config.bat file. find_program() does not usually look for a .bat file program unless explicitly specified in the NAMES argument. This would cause CMake to find the non-bat file, and executing that with execute_process() leads to a '%1 is not a valid Win32 application' error. Prefer to search for pkg-config.bat file when on a Windows host, in additiona to the regular pkg-config file. Fixes: #21239

* FindPkgConfig: Allow libraries that can't be found with their full pathChuck Atkins2019-09-161-1/+5
| | | | | | | | | | | | pkg-config's .pc files can sometimes provide libraries that are visible to the linker but not present in CMake's known search paths. In the case where CMake can find some, but not all of the library dependencies provided in a .pc file, this allows them to be passed through as "-lfoo" when the full path can't be found. This also removes the test failure cases that occured because of this scenario and adjsuts the remaining tests to account for not-found libraries
* FindPkgConfig: return the module found by pkg_search_moduleChristophe Giboudeaux2019-08-291-0/+7
| | | | | | | | | | When running `pkg_search_module`, it may be useful to get the matching module name in order to run `pkg_get_variable`. `pkg_search_module` now defines `<prefix>_MODULE_NAME` which contains the first matching module name. Fixes: #19648

* Help: Override pygments CMakeLexer to support <..> and [..]Joachim Wuttke (o)2018-10-181-10/+16
| | | | | | | | | | | | | | | | | | | | | | * The code snippets in the docs consist of CMake code mixed with syntax definition punctuation like < > [ ] ... Therefore a pure CMake lexer is inadequate. Here it is replaced by a CMake syntax definition parser. * Fixed syntax definition snippets in FindPkgConfig.cmake to make best use of syntax highlighting. This source file is the hardest to support because it contains comparison operators <= = >=, which need special attention to avoid confusion with the placeholder indicators <...>. * Fixed syntax in execute_process.rst (there were unbalanced brackets). * Disabled syntax highlighting for long string examples in cmake-language.7.rst. * No highlighting of removed syntax in CMP0049 * To inspect the outcome of this patch, see e.g. the pages * manual/cmake-buildsystem.7.html * module/ExternalProject.html * module/FindPkgConfig.html which are particularly rich in complex code snippets.

* FindPkgConfig: correct library search path for imported targets.Aleksandr Mezin2018-05-011-2/+6
| | | | | | | | | | | | | | `-L` in LDFLAGS doesn't mean that standard search paths should be excluded. Example: $ pkg-config --libs libmutter-2 -L/usr/lib/mutter -lmutter-2 -lgtk-3 -lgdk-3 -lmutter-clutter-2 -lcairo-gobject -latk-1.0 -lpangocairo-1.0 -lpango-1.0 -lfribidi -ljson-glib-1.0 -lgio-2.0 -lwayland-egl -lwayland-client -lXtst -lXi -lmutter-cogl-2 -lcairo -lgmodule-2.0 -pthread -lgdk_pixbuf-2.0 -lgobject-2.0 -lglib-2.0 -lgbm -ldrm -lwayland-server -lEGL -lXext -lXdamage -lXfixes -lXcomposite -lXrandr -lX11 Most of these libraries are located at standard paths, not in `/usr/lib/mutter`.

* FindPkgConfig: On FreeBSD search in `libdata/pkgconfig`Shin-ya Murakami2017-08-071-0/+3
| | | | | | The pkgconfig dir is placed at `${PREFIX}/libdata/pkgconfig` on FreeBSD instead of `${PREFIX}/lib/pkgconfig`, where `${PREFIX}` is `/usr/local` as default.
* FindPkgConfig: do not always rerun pkg_check_modules() with 2 argumentsRolf Eike Beer2017-07-101-1/+3
| | | | | | | | | | | | | | Since commit v3.8.0-rc1~47^2 (FindPkgConfig: Recheck pkg-config on parameter change, 2017-01-17) calling `pkg_check_modules` always re-runs. The problem is that if there are only 2 arguments passed to `pkg_check_modules```, then `_module0` will be set and `ARGN` will be empty. When this is written to cache it will be stored as just the value of `_module0` without any semicolon, so on the next run this doesn't match the expected value and the search is rerun. Revise the logic to handle the case of empty `ARGN` separately. Fixes: #17003

* FindPkgConfig: Fix pkg_check_modules() non-standard location searchYuriy Khokhulya2017-05-121-1/+3
| | | | | | | | | | | | | | | | | During search of the library file `pkg_check_modules()` attempts to find it in last specified library path in `${_prefix}_LDFLAGS`, that after dependency resolving contains path to standard location. So in case when `${_prefix}_LDFLAGS` has: -L/prefix;-L/usr/local/lib;-llibrary_from_prefix;-ldependency `library_from_prefix` will not be found. As solution need try to find the library in all paths preceding to the library. Fixes: #16873

* FindPkgConfig: Recheck pkg-config on parameter change.Matthew Hanna2017-01-251-1/+4
| | | | | | | | | Currently, once pkg_check_modules succeeds, it will never call _pkg_check_modules_internal again. That means that if the parameters to pkg_check_modules are changed, cmake will be called to reconfigure, but nothing will change. This change is to store the full string of arguments to pkg_check_modules and override the FOUND optimization so that the arguments are reevaluated when modified.
* FindPkgConfig: Fix missing error text when library version is specifiedGautier Pelloux-Prayer2016-11-281-1/+2
| | | | | | Calls like `pkg_check_modules(somelibrary>=3.22)` that specify a version requirement should still display an informative error when the package is not found. Fix our logic accordingly.
* PkgConfig: Fix FindPkgConfig imported target featureFlorent Castelli2016-11-041-1/+1
| | | | | | | The options to the find_library call to create the imported target used a literal string "HINTS /path NO_DEFAULT_PATH" instead of a list of options. This resulted in never finding any library in my testing.
* Simplify CMake per-source license noticesBrad King2016-09-271-16/+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.
