   1 # This is the cmake-based build system for Quassel IRC.
   2 # You may pass various options to cmake:
   3 # -DWANT_(CORE|QTCLIENT|MONO)=(ON|OFF)
   4 #                  : select binaries to build
   5 # -DQT=/path/to/qt : Choose a Qt4 installation to use instead of the system Qt4
   6 # -DSTATIC=ON      : Enable static building of Quassel. Use with care.
   7 # -DSPUTDEV=ON     : Do not use.
   8 # -DDEPLOY=ON      : Mac OS X only. Use only fore redistribution Quassel Packages!!
   9 #
  10 # NOTE: You need to remove CMakeCache.txt if you plan to change any of these values!
