 # -DQT=/path/to/qt : Choose a Qt4 installation to use instead of the system Qt4
-# -DSTATIC=1       : Enable static building of Quassel, most useful with a static Qt.
-# -DSTATICWIN=1    : Enable static building for Windows.
+# -DSTATIC         : Enable static building of Quassel. Use with care.
 # -DSPUTDEV        : Do not use.
