Viktor Szakats 8fce3e17e6 cmake: add CMake Config-based dependency detection ... After limiting `find_package()`/`find_dependency()` calls to curl local Find modules via the `MODULES` keyword, it became possible to detect dependencies via CMake Configs from within those local Find modules, by calling `find_package()` again with the `CONFIG` keyword. This patch implements this. Then maps detection results to the result variables and curl-specific imported targets the rest of the build expects. Also honor recently introduced `*_USE_STATIC_LIBS` (experimental) flags to map to the static target when requested. This adds CMake Configs as an alternative to the existing `pkg-config` and `find_path()`/`find_library()` auto-detection methods. Enabled by default for MSVC, outside vcpkg and when not cross-building. To enable for other cases, or override the default, you can use `-DCURL_USE_CMAKECONFIG=ON` or `OFF`. When enabled, Config detection happens after `pkg-config` and before `find_path()`/`find_library()`. Using CMake's built-in options, you may also manually point to the absolute directory holding Config files: `Libssh2_DIR`, `MbedTLS_DIR`, `NGHTTP2_DIR`, `NGHTTP3_DIR`, `NGTCP2_DIR` v1.19.0+ (with non-fork OpenSSL only), `Zstd_DIR` v1.4.5+ E.g. `-DMbedTLS_DIR=/path/to/mbedtls/lib/cmake/MbedTLS` These dependencies typically need to be built with CMake to support this. Tagged as experimental.
