# FindCaliper
# -----------
#
# Try to find the Caliper library
#
# This module defines the following variables:
#
#   Caliper_FOUND        - System has Caliper
#   Caliper_INCLUDE_DIRS - The Caliper include directory
#   Caliper_LIBRARIES    - Link these to use Caliper
#
# and the following imported targets:
#   Caliper::Caliper - The core Caliper library
#
# You can also set the following variable to help guide the search:
#   Caliper_ROOT - The install prefix for Caliper containing the
#                     include and lib folders
#                     Note: this can be set as a CMake variable or an
#                           environment variable.  If specified as a CMake
#                           variable, it will override any setting specified
#                           as an environment variable.
