@jcgruenhage , anyone: can you help with cross compile?

[jcgruenhage]

I don't see anything obvious going wrong here, rust is claiming to compile successfully...

[dkwo]

the cargo.sh script looks at build/target/release

cp: cannot stat '/builddir/fractal-4.4.2/build/target/release/fractal-gtk': No such file or directory
FAILED: fractal-gtk/src/fractal 
/builddir/fractal-4.4.2/scripts/cargo.sh .. fractal-gtk/src/fractal /builddir/fractal-4.4.2/build ''

while for cross we have e.g. build/target/aarch64-unkonwn-linux-gnu/release

$ ls masterdir/builddir/fractal-4.4.2/build/target/aarch64-unknown-linux-gnu/release/
build  deps  examples  fractal-gtk  fractal-gtk.d  incremental

i was trying to reinvent the wheel, the fix was already there..
