Alternatively you can create a package.
Like almost all store products are provided as packages.
These can contain you libraries, but optionally also example projects or help files (and any other files you would like to add).
Just download the package designer from the store: http://store.codesys.com/package-designer.html
After installation in CODESYS (Tools - package manager), you can start it through Tools - Package Designer.
It will require some testing to create a correct package, but it is a nice way to share your libraries and add any additional (required) libraries.
What can help, is to open another package (e.g. a library from the store), but make sure you use your own GUID and get one from an online guid generator.
