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!
