1 # - Find ROOT instalation
2 # This module tries to find the ROOT installation on your system.
3 # It tries to find the root-config script which gives you all the needed information.
4 # If the system variable ROOTSYS is set this is straight forward.
5 # If not the module uses the pathes given in ROOT_CONFIG_SEARCHPATH.
6 # If you need an other path you should add this path to this varaible.
7 # The root-config script is then used to detect basically everything else.
8 # This module defines a number of key variables and macros.
