+# - 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
