"The specified procedure could not be found." on Windows about assimp.jl

[heyx3]

Hi, I really want to use this for my framework but I'm on Windows and so I guess I need to update this package to the newest version of Assimp, which is 5.2.5.

However, I'm very new and still trying to get myself oriented in the world of BinaryBuilder. It seems like updating Assimp.jl is as simple as making a pull request in Yggdrasil to change build_tarballs.jl to point to the newer commit SHA? Which for the record is 9519a62dd20799c5493c638d1ef5a6f484e5faf1.

Glossing over the changelog for assimp, it doesn't seem like the API has changed, so is there anything else required beyond updating that single line in that single Julia build file? I'm happy to try and do it myself.

OK I tried making a pull request and Yggdrasil reports that we are implicitly supporting "experimental" platforms that weren't available the last time this package was updated, which is a problem because we aren't explicitly requiring Julia 1.6+.

So for now I'm going to disable the experimental platforms, which I think just leaves us with the platform support of the earlier version of Assimp.jl.

Fixed the previous issue, but now the build leads to a warning about improper use of offsetof(), and the compiler is configured to treat all warnings as errors. Based on some googling, I think this warning is ignorable, but I'm not sure how to get Yggrasil to go along with that.

Related to this topic, the release notes for Assimp 5.2.5 says they now support GCC v12. Should we update/remove the setting preferred_gcc_version=v"7" in build_tarballs.jl?

(I hope this isn't spammy? I just like documenting my struggles in case me or somebody else has to deal with a similar problem in the future)

I updated the preferred GCC version to v12 and now only a few specific platforms fail to compile due to warnings. I updated the script to explicitly forbid those platforms. And maybe we should raise a ticket with assimp about those build configurations.

p != Platform("i686", "linux"; libc="musl") &&
                                                 p != Platform("armv7l", "linux"; libc="musl") &&
                                                 p != Platform("aarch64", "macos") &&
                                                 p != Platform("x86_64", "macos") &&
                                                 p != Platform("powerpc64le", "linux"; libc="glibc")

Still waiting for Yggdrasil to finish, but things are looking good!
