Allow finding newer versions of podio (for EDM4hep IO)

[jmcarcell]

After podio changed to 1.0.0 (see https://github.com/AIDASoft/podio/commit/072c7dce699a2dc90f225cb0a75a4f2ce9677cf8), cmake won't run when asking for version 0.16.3. I think we can remove the requirement and let the build systems figure which versions are compatible with which.

The error when configuring is:

  >> 61    CMake Error at CMakeLists.txt:158 (find_package):
     62      Could not find a configuration file for package "podio" that is co

I disagree with this approach of removing dependency version information. DD4hep requires a certain set of podio features, namely those provided by 0.16.3. Podio promises (through the SameMajorVersion policy) that any newer version with same major version can be expected to provide those features, but a different major version does not come with that promise. Failing on build configuration when you attempt to use podio 1.0.0 is exactly what should happen here.

Podio could change the policy to AnyNewerVersion (which then essentially means that you cannot use major version updates to remove API functionality).

Can someone remind me again, why we search explicitly for podio and not just EDM4hep here?

This is because of the need for podio::Frame support (https://github.com/AIDASoft/DD4hep/commit/57a7bf2f20f38b27b854ecbc1554af047fc40b85), which EDM4hep separately doesn't care about.
