libQt5Core.so.5: cannot open shared object file

I’ve just installed snapd and a snap package called skrooge. When i try to run skrooge it says:

skrooge: error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory

I thought that all libraries should be included in the package. Is it a bug in the package or in the snapd, or maybe I’ve done something wrong?
