This fixes builds in projects that compile OpenImageIO as static libraries and don't themselves depend on the image libraries used by OpenImageIO such as PNG, JPEG or TIFF.

When OpenImageIO is built as a static library its targets have e.g. PNG::PNG among INTERFACE_LINK_LIBRARIES. If the including project does not itself depend on PNG, the following error would be observed:

Target "<...>" links to target "PNG::PNG" but the target was not found.
Perhaps a find_package() call is missing for an IMPORTED target, 
or an ALIAS target is missing?

Checklist:

  • I have read the contribution guidelines.
  • If this is more extensive than a small change to existing code, I
    have previously submitted a Contributor License Agreement
    (individual, and if there is any way my
    employers might think my programming belongs to them, then also
    corporate).
  • [not needed] I have updated the documentation, if applicable.
  • [not needed] I have ensured that the change is tested somewhere in the testsuite
    (adding new test cases if necessary).
  • My code follows the prevailing code style of this project.

2.4.3.0-RC2 second release candidate
3162d05 
Changes since RC1:

  - ImageCache/TextureSystem both have added a `getattributetype()`
    method, which retrieves just the type of a named attribute. AcademySoftwareFoundation#3559
    (2.4.4.0)  NOTE: THIS IS AN ABI BREAKING CHANGE
  - Python: Fix the ability to `getattribute()` of int64 and uint64
    metadata or attributes. AcademySoftwareFoundation#3555 (2.4.4.0)
  - Build: Improvements to the generated cmake config files when
    building static libraries. AcademySoftwareFoundation#3552 AcademySoftwareFoundation#3557 (2.4.4.0)
  - Support for gcc 12.1. AcademySoftwareFoundation#3480 (2.4.2.1) AcademySoftwareFoundation#3551 (2.4.4.0)
  - Support building with clang 15.0. AcademySoftwareFoundation#3563 (2.4.4.0)
  - Fix cross-compiling on Android failing due to `-latomic` check. AcademySoftwareFoundation#3560
    (2.4.4.0)
  - Fix building on iOS. AcademySoftwareFoundation#3562 (2.4.4.0)

Note that we bumped the version to from 2.4.3.x 2.4.4.0 to reflect the
ABI break introduced by the last minute by the IC/TS addition of a new
virtual function. ABI will not change again for 2.4.
