I see only one download for IUP, not many. The GPL license appears to say that ALL code linked with GPL source (that would mean all the GPL static libraries), must also be disclosed under a GPL license. By providing GPL static libraries in a single IUP package instead of having the users download it separately (which is what "split" would actually mean), it seems to me that it might a violation of the GPL license.
But I'm not a lawyer or the author of GPL, so maybe someone else can tell us if this is legit? Maybe someone like Richard Stallman, which Google lists as the author of GPL?

That's exactly why we split in several libraries. Each secondary library can have its own license if necessary. The documentation of each library reflects this. BTW the documentation cleary displays "Additional" for controls that are available in secondary libraries.

It is not reasonable to expect users of IUP to comb through each and every source file to search for any licensing that was not mentioned at the outset in the documentation. At a minimum, I would expect to see third party licensees given credit where credit is due under Products➜Credits in the online WebBook, but there is none, as if they didn't exist. >From what I've seen from Tysen Moore, IUP is not a standalone product but a software framework that, depending on how you use it, requires more than one Copyright/License to use, instead of just the one listed in the WebBook. It makes the IUP Copyright/License look misleading because it isn't the whole entire license for the entire framework, it is just part of one of many licenses but they don't say which parts that license applies to. Are you sure that what IUP is doing is legal?

But no, they are documented only at their respective IUP library page. BTW if you red the COPYRIGHT files, then you actually red their licenses too. Unfortunately legality text is confusing.

I can't seem to find the third party licenses in the documentation (https://www.tecgraf.puc-rio.br/iup/). I have also checked the various "COPYRIGHT" and "README" files and can't find anything either. It would be useful to have the "Overview" documentation that reads, "IUP is free software, can be used for public and commercial applications." also mention to go to the "Copyright/License" section for the some exceptions. Then within the "Copyright/License" section of the documentation it could list the third party licenses.
