In the latest release of OSGeo4W they list the #curl license as "non-open-source"... 🤔
@bagder
Fixed
@jef thanks!
@bagder Hey @jef , the good thing is that you can actually completely omit that – the user doesn't have to zustimmen (agree) to anything; the curl license doesn't require your installer to show that text at all there (think about it: does someone buying a fancy coffee machine have to agree to the curl license? Do you, on Linux, agree to the curl license when installing debian (or any other modern distro)?); just ship the license, anywhere https://curl.se/docs/faq.html#what-are-my-obligations-when-using-libcurl-in-my-commercial-apps, or change agreement->notice :)

@funkylab
Well, it includes all licences, and most of them are whitelisted as free, there also several md5 checksum entries for curl on that list - but somehow the latest accidentally disappeared somehow. The fix was to put it back.
