engine uses final (?) SDL 2 APIs, new events and types added. Touch input broke by the way, and system events should be handled differently
As a special exception, FreeType can also be built with the 'makepp'
build tool, available from http://makepp.sourceforge.net.
Note, however. that you will need at least version 1.19 and pass the
option --norc-substitution to have it work correctly.
