# rustflags must be exported again at install as cargo build will
# rebuild the project if it detects flags have changed (to none or other)
export RUSTFLAGS="%{rustflags}"
# install stage also requires re-export of 'cargo-home' or cargo
# will try to download source deps and rebuild
export CARGO_HOME=`pwd`/cargo-home/
# cargo install appends /bin to the path
cargo install --root=%{buildroot}%{_prefix}
