sixel-sys's Issues

Can't compile sixel-sys on windows or macOS (works fine in linux)

On Windows: I get this error:

rror: failed to run custom build command for `sixel-sys v0.3.1`

Caused by:
  process didn't exit successfully: `V:\Documents\viuertest\sixel-sys-test\target\debug\build\sixel-sys-f5b3ec906222e763\build-script-build` (exit code: 101)
  --- stdout
  cargo:rustc-link-lib=dylib=sixel
  cargo:rustc-link-search=native=V:\Documents\viuertest\sixel-sys-test\target\debug\build\sixel-sys-060e93a697b4af5b\out\lib

  --- stderr
  thread 'main' panicked at 'Failed to execute ./configure: Os { code: 2, kind: NotFound, message: "The system cannot find the file specified." }', C:\Users\micha\.cargo\registry\src\github.com-1ecc6299db9ec823\sixel-sys-0.3.1\build.rs:71:22

On macOS I get this:

--- stderr
thread 'main' panicked at 'Failed to execute ./configure: OS {code: 2, kind: NotFound, message: "No such file or directory" }', /users/michaelmulet/.cargo/registry/src/github.com-1ecc6299db9ec823/sixel-sys-0.3.1/build.rs:71:22
configure: WARNING: unrecognized options: --without-python
configure : WARNING: unrecognized options: --without-python

If I try to build with RUST_BACKTRACE=1, then it says the error is at

build_script_build::main
at ./build.rs:71:9

Tracing it backwards, that just tells us that configure failed.

System library compiled at compile time is not available at runtime

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.
