#
# - Find HQR include dirs and libraries
# Use this module by invoking find_package with the form:
# find_package(HQR
# [REQUIRED]) # Fail with error if hqr is not found
#
# This module finds headers and hqr library.
# Results are reported in variables:
# HQR_FOUND - True if headers and requested libraries were found
# HQR_INCLUDE_DIRS - hqr include directories
# HQR_LIBRARY_DIRS - Link directories for hqr libraries
# HQR_LIBRARIES - hqr component libraries to be linked
#
# The user can give specific paths where to find the libraries adding cmake
# options at configure (ex: cmake path/to/project -DHQR_DIR=path/to/hqr):
# HQR_DIR - Where to find the base directory of hqr
# HQR_INCDIR - Where to find the header files
# HQR_LIBDIR - Where to find the library files
# The module can also look for the following environment variables if paths
# are not given as cmake variable: HQR_DIR, HQR_INCDIR, HQR_LIBDIR
