Via these variables, as lists:
- `CURL_SUPPORTED_PROTOCOLS`
- `CURL_SUPPORTED_FEATURES`
As individual flags:
- `CURL_SUPPORTS_<protocol/feature>` = `TRUE`
Also:
- set `CURL_VERSION_STRING` which was missing when using
`find_package(CURL CONFIG)` or
`find_package(CURL NO_MODULE)`.
- set `CURL_<prototol/feature>_FOUND` for compatibility.
- show full list of missing but required `COMPONENTS`.

Fixes#15854Closes#15858
This reverts commit 39c06f7883#15005.
Combined with most Find modules now supporting `pkg-config`
(39c741b7b0#15408) this change made
mingw-cross builds fragile by picking up OS-native components. Also
adding `/usr/include` to the header path, confusing feature detection.
Enable `CURL_USE_PKGCONFIG` by default for MinGW cross-builds.
Note: This may cause fallouts in certain envs where `pkg-config` picks
up native packages.

- unroll two short loops.
- unfold lines.
- merge lines with their comments.
- add missing quotes.
- tidy up grammar in error/warning messages.
Cherry-picked from #14692Closes#14998
Enable `CURL_USE_PKGCONFIG` by default for more environments:
- for `MINGW` targets when not using cross-compilation.
- stop restricting vcpkg to MSVC. (this currently unlocks mingw,
also unlocked by the update above.)
Also:
- cache `CURL_USE_PKGCONFIG` in `CURLConfig.cmake`.

- drop redundant internal variable `USE_ZLIB`, rely on `HAVE_LIBZ`.
- rename `optional_dependency()` -> `curl_dependency_option()`
Make `grep 'option('` hit this option. Namespaced.
It has a single use with `ZLIB`.
Closes#14918
- show `OpenSSL v3+` when detected (as in `./configure`).
(this string also makes its way to `curl-config`.)
- prefer `unset(VAR)` over `set(VAR)`.
Same effect, but `unset()` tells the intent unambiguously.

- drop "implementation" from an `option()` description.
- FindGSS: replace legacy keyword alias with modern alternative.
https://cmake.org/cmake/help/latest/command/get_filename_component.html
- move `CURL_STATIC_CRT` logic next to its `option()`.
- improve order of `libcurl.pc`/`curl-config` variable init lines.
- tests: drop/shorten custom target names.
They inflated generated make files by 550KB.
Keep target name logic for sync between code snippets.
Follow-up to a2ef5d36b3#14660
- clear a variable after use.
- restore `STATUS` for `Features:`/`Protocols:` `message()`s:
Without it the output goes to stderr, and appears in red in CMake GUI.
It doesn't seem possible to show a line on stdout without leading
underscores to match `curl -V` and `./configure` output.
Partial revert of acbc6b703f#14197
- WindowsCache: move `HAVE_LINUX_TCP_H` into the header group.
- move strings to the same line as their `STRING` keyword.
- formatting in generated code.
- delete bogus comment.
- unfold lines for readability.
- fix a too long line. (for cmakelint)
- missing quotes, whitespace, comments.
Closes#14610
Limits `pkg-config` to UNIX and MSVC with vcpkg, by default. Compared to
curl 8.9.1, this unlocks `pkg-config` on MSVC with vcpkg.
This condition might be updated in the future depending on where
`pkg-config` can be useful without breaking things. (e.g. to non-cross
MINGW, or all MINGW).
In the meantime everyone is free to override the default and test their
build with `pkg-config` by setting the `CURL_USE_PKGCONFIG=ON` CMake
option.
Closes#14575
Add option to control whether to use `pkg-config` to detect
dependencies. Curl's CMake uses `pkg-config` by default for all targets
except for MSVC without vcpkg.
With the CMake option `-DCURL_USE_PKGCONFIG=ON` you can override it to
use `pkg-config` always.
If `pkg-config` is causing issues, e.g. in cross-builds or other cases,
`-DCURL_USE_PKGCONFIG=OFF` disables all use of `pkg-config`.
Also add it to `curl-config.cmake`. Not yet used, but will be once curl
starts referencing any curl-specific `Find*` module from this public
script.

Fixes errors on second `find_package(CURL)`. This is a frequent case
with transitive dependencies:
```
CMake Error at ...:
add_library cannot create ALIAS target "CURL::libcurl" because another
target with the same name already exists.
```
Test to reproduce:
```cmake
cmake_minimum_required(VERSION 3.27) # must be 3.18 or higher
project(curl)
set(CURL_DIR "example/lib/cmake/CURL/")
find_package(CURL CONFIG REQUIRED)
find_package(CURL CONFIG REQUIRED) # fails
add_executable(main main.c)
target_link_libraries(main CURL::libcurl)
```

Closes#11913
This patch adds the ability to build a static and shared libcurl library
in a single build session. It also adds an option to select which one to
use when building the curl executable.
New build options:
- `BUILD_STATIC_LIBS`. Default: `OFF`.
Enabled automatically if `BUILD_SHARED_LIBS` is `OFF`.
- `BUILD_STATIC_CURL`. Default: `OFF`.
Requires `BUILD_STATIC_LIBS` enabled.
Enabled automatically if building static libcurl only.
- `STATIC_LIB_SUFFIX`. Default: empty.
- `IMPORT_LIB_SUFFIX`. Default: `_imp` if implib filename would collide
with static lib name (typically with MSVC) in Windows builds.
Otherwise empty.
Also:
- Stop setting the `CURL_STATICLIB` macro via `curl_config.h`, and pass
it directly to the compiler. This also allows to delete a condition
from `tests/server/CMakeLists.txt`.
- Complete a TODO by following the logic used in autotools (also for
`LIBCURL_NO_SHARED`), and set `-DCURL_STATICLIB` in `Cflags:` of
`libcurl.pc` for _static-only_ curl builds.
- Convert an existing CI test to build both shared and static libcurl.
Closes#11505
- they are mostly pointless in all major jurisdictions
- many big corporations and projects already don't use them
- saves us from pointless churn
- git keeps history for us
- the year range is kept in COPYING
checksrc is updated to allow non-year using copyright statements
Closes#10205
Add licensing and copyright information for all files in this repository. This
either happens in the file itself as a comment header or in the file
`.reuse/dep5`.
This commit also adds a Github workflow to check pull requests and adapts
copyright.pl to the changes.
Closes#8869
Reported by the new script 'scripts/copyright.pl'. The script has a
regex whitelist for the files that don't need copyright headers.
Removed three (mostly usesless) README files from docs/
Closes#5141
Use 'GNUInstallDirs' standard module to set destinations of installed
files.
Use uppercase "CURL" names instead of lowercase "curl" to match standard
'FindCURL.cmake' CMake module:
* https://cmake.org/cmake/help/latest/module/FindCURL.html
Meaning:
* Install 'CURLConfig.cmake' instead of 'curl-config.cmake'
* User should call 'find_package(CURL)' instead of 'find_package(curl)'
Use 'configure_package_config_file' function to generate
'CURLConfig.cmake' file. This will make 'curl-config.cmake.in' template
file smaller and handle components better. E.g. current configuration
report no error if user specified unknown components (note: new
configuration expects no components, report error if user will try to
specify any).
Closes https://github.com/curl/curl/pull/2849
