IIUC there’s a bundled copy of SDL, right?  Can we instead build against
our SDL?

Ideally, to be safe from bundling, we should “rm -rf ThirdParty” in a
snippet.  Is that possible?

Please use a literal string in the ‘substitute*’ pattern (you can use
backslashes to split it on several lines.)

Full sentences please!  :-)

Could you send an updated path?

Thank you,
