can compile engine as library on linux but not run the executable (automatically), most likely breaking other platforms (wrt engine-as-library)
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.
