dnl Autoconf macro to check for existence or ROOT on the system
dnl Synopsis:
dnl
dnl ROOT_PATH([MINIMUM-VERSION, [ACTION-IF-FOUND, [ACTION-IF-NOT-FOUND]]])
dnl
dnl Some examples:
dnl
dnl ROOT_PATH(3.03/05, , AC_MSG_ERROR(Your ROOT version is too old))
dnl ROOT_PATH(, AC_DEFINE([HAVE_ROOT]))
dnl
dnl The macro defines the following substitution variables
dnl
dnl ROOTCONF full path to root-config
dnl ROOTEXEC full path to root
dnl ROOTCINT full path to rootcint
dnl ROOTLIBDIR Where the ROOT libraries are
dnl ROOTINCDIR Where the ROOT headers are
dnl ROOTCFLAGS Extra compiler flags
dnl ROOTLIBS ROOT basic libraries
dnl ROOTGLIBS ROOT basic + GUI libraries
dnl ROOTAUXLIBS Auxilary libraries and linker flags for ROOT
dnl ROOTAUXCFLAGS Auxilary compiler flags
dnl ROOTRPATH Same as ROOTLIBDIR
dnl
dnl The macro will fail if root-config and rootcint isn't found.
