You don’t need to specify `--target=` unless you are building the toolchain 
(binutils/gcc) itself. Normal libraries and apps only need `—-host=`.

You can, but you are probably better off adding 
`—-prefix=/home/jack/mxe/mxe/usr/i686-w64-mingw32.static`
to `configure` and running `make install`.

It’s hard to say, the standard lib paths will find any manually specified 
`-lcapnproto -lfoo` etc. but 
if you haven’t run `make install` then the components required for automatic 
detection (a `capnproto.pc`
or FindCapnProto.cmake file) won’t be available.
