83dnl Autoconf macro to check for existence or ROOT on the system
84dnl Synopsis:
85dnl
86dnl ROOT_PATH([MINIMUM-VERSION, [ACTION-IF-FOUND, [ACTION-IF-NOT-FOUND]]])
87dnl
88dnl Some examples:
89dnl
90dnl ROOT_PATH(3.03/05, , AC_MSG_ERROR(Your ROOT version is too old))
91dnl ROOT_PATH(, AC_DEFINE([HAVE_ROOT]))
92dnl
93dnl The macro defines the following substitution variables
94dnl
95dnl ROOTCONF full path to root-config
96dnl ROOTEXEC full path to root
97dnl ROOTCINT full path to rootcint
98dnl ROOTLIBDIR Where the ROOT libraries are
99dnl ROOTINCDIR Where the ROOT headers are
100dnl ROOTCFLAGS Extra compiler flags
101dnl ROOTLIBS ROOT basic libraries
102dnl ROOTGLIBS ROOT basic + GUI libraries
103dnl ROOTAUXLIBS Auxilary libraries and linker flags for ROOT
104dnl ROOTAUXCFLAGS Auxilary compiler flags
105dnl ROOTRPATH Same as ROOTLIBDIR
106dnl
107dnl The macro will fail if root-config and rootcint isn't found.
