# - Config file for the CLHEP package
# It defines the following variables
# CLHEP_INCLUDE_DIRS - include directories for CLHEP
# CLHEP_DEFINITIONS - compile definitions needed to use CLHEP
# CLHEP_LIBRARIES - libraries to link against
#
# CLHEP is built concurrently as a single library and as a set of component
# libraries. At present, this config file is only designed to configure
# the single main library in static or shared mode.
#
# The following per-component variables are set:
#
# CLHEP_${COMPONENT}_FOUND True if CLHEP library mode "component"
# was found
#
# CLHEP_${COMPONENT}_LIBRARY Contains the library for specified mode
# "component"
#
# CLHEP current only supports two components: static and shared, which
# represent the two possible library modes that the main CLHEP library
# is built in.
#
# You can call find_package with 'static' or 'shared' as component arguments
# to pick a particular library mode of CLHEP. For example
#
# find_package(CLHEP REQUIRED static)
#
# will set CLHEP_LIBRARIES to the CLHEP static library.
#
# If you do not specify a shared or static component argument, shared
# libraries will be selected by default.
#
# ===========================================================================
# Variables used by this module which can change the default behaviour of
# this module. They need to be set prior to the call to find_package
#
# CLHEP_CONFIG_DEBUG - If set, this will enable some output from this module
# to help in debugging it behaviour
#
#----------------------------------------------------------------------------
# ---------------------------------------------------------------------------
# Print out values of the variables that we expect find_package to have passed
# to us. This is useful for developers of CLHEPConfig!
