System library compiled at compile time is not available at runtime

[msrd0]

This crate builds a dynamic version of libsixel at compile time and links against it. Then, when you run the executable, that library is not found, and relies on you having a dynamic library of libsixel installed on the operating system.

Please change it so that if libsixel is installed, you use the system installed version, and otherwise you compile and statically link against your own compiled version of libsixel. This is how many popular sys crates work in the Rust ecosystem, for example libgit2-sys.
