The apparent issue you are missing is that you are calling native app from
Cygwin environment.
Each have its own rules, and to have it working with minimal issues, you'd
need to satisfy both sides.
In specific case, PATH is a special environment variable for both sides, and
you have to correctly translate it from one side to the other.

cygpath helps. As you have figured out already.

I provided a wrapper script I use myself, you could add any massaging to it
that you feel necessary. Like `unset TERM` or PATH modifications.
