-    As noted above, building Qt 5 with QNX SDP 6.5.0 SP1 requires the Screen. Qt 5 needs
-    related headers and libraries and will not build if they are not available. QNX SDP 6.5.0 SP1
-    contains an older version of SQLite which is not supported by Qt 5 anymore. You should use the
-    SQLite provided with the Qt 5 source code. This is the default behavior of \c{configure} anyway,
-    just do not force the system SQLite with \c{-system-sqlite}. QNX SDP 6.5.0 SP1 does not provide
-    fontconfig. Qt will fall back to its internal font database. This limits the flexibility with
-    handling fonts, but it is not a serious issue for most projects. Many other Qt 5 add-on modules
-    will probably not build with QNX SDP 6.5.0 SP1, since their development has advanced too far
-    to support that older release of SDP.
