0.9.0: cmake fails because it wants to use bubdled libraries

**Describe the bug**

Looks like just released 0.9.0 no longer wants to use system libraries and wants to use ONLY bundled libraries.



**To Reproduce**

Build 0.9.0 out of autogenerated from git tag tar ball which has no included git subrepos source code in third_party/



**Expected behavior**

Up to now it was possible to build libjxl against system installed libraries.

Looks like new version dropped that behaviour.

All used libraries have proper pkgconfig interface which allows detect and use system installed libraries.
