After limiting `find_package()`/`find_dependency()` calls to libssh2 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 libssh2-specific imported targets the rest of the build expects. 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 `-DLIBSSH2_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: `MbedTLS_DIR`, `wolfssl_DIR` E.g. `-DMbedTLS_DIR=/path/to/mbedtls/lib/cmake/MbedTLS` mbedTLS needs to be built with CMake for this to work. wolfSSL 5.9.0+ also supports it when it was built with autotools. Experimental. Refs:8fce3e17e6https://github.com/curl/curl/pull/20814a56ab9dbc8https://github.com/curl/curl/pull/21098 Follow-up todd5f3fff39#2262 Closes #2264
