Linking

If libwebp is found in the system, it links against the library. Otherwise it builds and links against the bundled libwebp.

In these cases, static link is preferred:

• For musl target.
• When cross-compiling.
• static feature is turned on.
• LIBWEBP_SYS_STATIC environment variable is set to 1 when building.
