Fix root and example project Makefiles.

[mattpolzin]

Fixes #26.

• fix root makefile to substitute correct string when setting the ncurses version.
• fix example makefiles to pull all local depends and libs.

Yep, the pumpkin now works just fine! I do get an error during the build:

cp: cannot stat '../../support/*.dylib': No such file or directory

I suppose we could maybe use cp ../../support/libncurses* ./depends/ncurses-idris-0/lib/ instead of the disjunction?

That should be a good solve. I'm surprised the disjunction errors though. Maybe it prints a message but doesn't technically error out (exit code 1)? The whole point of using || was to do something with a non-zero code rather than give up.

My bad, you're right: it prints the error message but it's not counted as an error.

I think I'll merge this & your PR first and come back in one sweep after to change it all over to your idea to clean up the error message.

Thanks for your help in figuring this problem out!
