USE_WXNEEDED. cmake hacks/fixes for QtWebKit fixes being looked by dcoppa@..
Trojita is a fast Qt IMAP e-mail client. It offers on-demand message
list and body part loading, offline IMAP support, IMAP over SSH (in
addition to the usual SSL/TLS connections) and deals with HTML mail in a
safe and robust way.
