Full Changelog: v5.3.1...v6.0.1

---

This discussion was created from the release The Assimp 6.0.1 Bugfix Release.

[sagaceilo]

Just wonder - if Win platform build should contain a .lib file as well. This way You essentially don't have to compile whole thing on Your own as it is a complete package. No big deal for me, as I'm compiling whole thing anyway, but for some...

[kimkulling]

In my expectation the following binaries will be generated on Windows:

- bin\<Config>\*dll / *exe
- lib\ *lib

[kimkulling]

This will be the base configuration for a shared library build. If you are using static linkage there will be no dlls at all.

[Begasus]

Thanks on the update, Haiku's port has been updated. 👍

[Osyotr]

Should

Line 505 in b3a47a6

write_basic_package_version_file("${VERSION_CONFIG}" COMPATIBILITY SameMajorVersion)

use AnyNewerVersion instead of SameMajorVersion?
I'm seeing some regressions in vcpkg due to this.
