When building podio, use target_include_directories to set its build and install time header paths. Use of include_directories is retained in scripts due to ROOT's dictionary generation not supporting usage requirements until version 6.18. Update podioConfig to use full CMakePackageConfigHelpers system: - Automatic self-location - No hard coded install time paths - Re-find ROOT dependency - Proper imported target for libpodio These mean that a podio client can, in CMake, do ```cmake find_package(podio REQUIRED) add_executable(foo foo.cc) target_link_libraries(foo podio::podio) ``` and all include/link paths will be set correctly.

Excellent, this line (left over from boilerplate) forced us to use a custom FindPodio script, great that this is gone.

Thanks @vvolkl ! I've just realised I left a debug |
Remove extraneous debugging message() call. Set additional interface include directories for podio imported target with set_property per CMake recommendations.

Looks good to me - will merge. |

The changes introduced by AIDASoft#54 caused installs to fail due to the change in location of the templates directory relative to python/. Following discussion in AIDASoft#58, implement simplest possible change to fix by moving templates inside the python directory. Retain this layout at install time, adjusting the `template_dir` variable in podio_class_generator.py accordingly. Fixes: AIDASoft#58

This replaces the horribly out of date #29. key4hep/EDM4hep#1 identified a few issues in the way Podio is built and creates its CMake config files for downstream clients. This PR aims to address some of these by:
podioConfig.cmakefile and associatedpodioTargets.cmakeThese mean that a podio client can, in CMake, do
and all include/link paths will be set correctly.
I wasn't sure how to address install of the Python code as this appears split between program and library code (e.g.
podio_class_generator.pyshould probably go in theCMAKE_INSTALL_BINDIRlocation, whereaspodio_config_reader.pyis more a Python module). Part of this would be to allowpodio_class_generator.pyto be supplied as a CMake imported target together with a CMake function to run code generation, but see the info in #29 on issues here.BEGINRELEASENOTES
