It doesn't really matter in this case - it matters really only for FindLibXml2, because `PROJECT_SOURCE_DIR` point to svgfill, when it's config executed, instead of `CMAKE_SOURCE_DIR` - so `CMAKE_SOURCE_DIR ` is never removed from the path, leading to cyclic calls. Adding for HDF5 too just for consistency.
Noticed testing command from #7277. I believe Serializers it not actually needed to build IfcGeomServer.
Example error:
```
/usr/bin/ld: cannot find -lSerializers: No such file or directory
```
The issue was with ci.yml - it was using system boost shared libraries (since Boost_USE_STATIC_LIBS by default is OFF), but CGALConfig was overriding leading to compilation issues.
Not sure why it occurred only now, maybe after recent changes with shared libraries this problem just got more apparent and previously it was masked by some other library after mappings also using IfcGeom.
But the issue was that mapping were not linked against IfcGeom, though it's symbols were used in them. E.g. IfcSectionedSurface.cpp was using `has_loft` from `infra_sweep_helper`.
Issue occurred only on Linux - msvc and clang are less strict and probably do multiple passes to fetch symbols.
Example errors:

cmake configs seems to be provided with the default installation, so `find_package` should do the job that `find_path` and `find_library` did previously.
Previously we were setting `HDF5_LIBRARIES` explicitly, but I'm not sure if really worked, since we never set `HDF5_INCLUDE_DIR` and user would have to provide it manually either way.
`find_package(HDF5)` will search for default paths and will set `HDF5_LIBRARIES` and `HDF5_INCLUDE_DIR` automatically.
