-#                    of "core", "client", "mono" or "all".
-# -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.
-# -DSPUTDEV        : Do not use.
+# -DWANT_(CORE|QTCLIENT|MONO)=(ON|OFF)
+#                        : select binaries to build
+# -DWITH_OPENSSL=OFF     : Disable OpenSSL support
