how do I install modules into my project?
I have installed dub and tried doing "dub add tkd" and "dub install tkd" to install this library https://github.com/nomad-software/tkd however I get this error when building..

Severity Code	Description	Project	File	Line	Suppression State
Error	module `tkdapplication` is in file 'tkd\tkdapplication.d' which cannot be read

I am using visual d for visual studio 2019
