rpath is not set for Qt library built in cargo_without_cmake #224

When using the cargo_without_cmake example if qmake is in your PATH but the libraries are not in normal LD search locations. Then CMake works by using rpath's to point to the Qt libraries (?).

This is not possible with cargo yet due to https://github.com/rust-lang/cargo/issues/5077

For now the workaround is to add the Qt libraries path to your LD_LIBRARY_PATH environment variable.

Maybe rustc already supports this? https://doc.rust-lang.org/rustc/codegen-options/index.html#rpath
