 # This is the cmake-based build system for Quassel IRC.
+# You may pass various options to cmake:
+# -DBUILD=<string> : Select binaries to build. <string> may contain any combination
+#                    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.
+# -DSPUTDEV        : Do not use.
+#
+# NOTE: You need to remove CMakeCache.txt if you plan to change any of these values!
