+# - Find HWLOC include dirs and libraries
+# Use this module by invoking find_package with the form:
+# find_package(HWLOC
+# [REQUIRED]) # Fail with error if hwloc is not found
+#
+# This module finds headers and hwloc library.
+# Results are reported in variables:
+# HWLOC_FOUND - True if headers and requested libraries were found
+# HWLOC_INCLUDE_DIRS - hwloc include directories
+# HWLOC_LIBRARY_DIRS - Link directories for hwloc libraries
+# HWLOC_LIBRARIES - hwloc 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 -DHWLOC_DIR=path/to/hwloc):
+# HWLOC_DIR - Where to find the base directory of hwloc
+# HWLOC_INCDIR - Where to find the header files
+# HWLOC_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: HWLOC_DIR, HWLOC_INCDIR, HWLOC_LIBDIR
