Indeed, there seems to be a problem with paths in OpenBabel CMake
modules. OpenBabel3Config.cmake seems suspicious: ${OpenBabel3_DIR} does
not seem to be set anywhere, and the following paths too get incorrect
values:

* OpenBabel3_INCLUDE_DIRS: should be /usr/include/openbabel3
* OpenBabel3_EXPORTS_FILE: should be
/usr/lib/<triplet>/cmake/openbabel3/OpenBabel3_EXPORTS.cmake
* OpenBabel3_LIBRARIES (maybe?)

Not sure if this issue is relevant outside Debian, hence the upstream
confusion. I would suggest patching OpenBabel CMake modules in Debian. I
volunteer to do that if no one comes up with a better solution.

Best,
Andrius
