```
DICOM disabled because there's a check for dcmtk which isn't a dependency of osg[plugins]
Inventor disabled because there's a check for this library.
Opencascade disabled because it's broken.
All others disabled because they were behind some kind of if (XXX_found) in src\osgPlugins\CMakeLists.tx, except, Quicktime left alone because that's part of MacOS?
* [many ports] call vcpkg_fixup_pkgconfig()
The ports generate pc files, but don't call vcpkg_fixup_pkgconfig() so that there are absolute paths in the pc files
* Update port-version for armadillo and polyclipping.
* Update version database.
