Via options: - `BROTLI_USE_STATIC_LIBS` - `CARES_USE_STATIC_LIBS` - `LIBSSH_USE_STATIC_LIBS` - `LIBSSH2_USE_STATIC_LIBS` - `MBEDTLS_USE_STATIC_LIBS` - `NGHTTP2_USE_STATIC_LIBS` - `NGHTTP3_USE_STATIC_LIBS` - `NGTCP2_USE_STATIC_LIBS` - `ZSTD_USE_STATIC_LIBS` When enabled, make a "best effort" finding static libs first and set the "build static" macro (on Windows) as required by the dependency. When doing `pkg-config`-based detections, make curl select the static configuration, which shall set the "build static" macro also. These options resemble CMake's `OPENSSL_USE_STATIC_LIBS` and `ZLIB_USE_STATIC_LIBS` (the latter does not support `pkg-config` as of CMake v4.2.2). Shared/static library selection based on loose filename conventions is fragile and prone to break if the non-static-suffixed library is found and happens to be a shared library, or, if the linker decides to pick up a shared copy (e.g. `.a.dll`) that shadows the static one. It may help to provide either static or shared, but not both, on the disk, and match that with this setting. Experimental. Ref: #20013 Closes #20015
