+# - Find HWLOC include dirs and libraries
|
|
12
|
+# Use this module by invoking find_package with the form:
|
|
13
|
+# find_package(HWLOC
|
|
14
|
+# [REQUIRED]) # Fail with error if hwloc is not found
|
|
15
|
+#
|
|
16
|
+# This module finds headers and hwloc library.
|
|
17
|
+# Results are reported in variables:
|
|
18
|
+# HWLOC_FOUND - True if headers and requested libraries were found
|
|
19
|
+# HWLOC_INCLUDE_DIRS - hwloc include directories
|
|
20
|
+# HWLOC_LIBRARY_DIRS - Link directories for hwloc libraries
|
|
21
|
+# HWLOC_LIBRARIES - hwloc component libraries to be linked
|
|
22
|
+#
|
|
23
|
+# The user can give specific paths where to find the libraries adding cmake
|
|
24
|
+# options at configure (ex: cmake path/to/project -DHWLOC_DIR=path/to/hwloc):
|
|
25
|
+# HWLOC_DIR - Where to find the base directory of hwloc
|
|
26
|
+# HWLOC_INCDIR - Where to find the header files
|
|
27
|
+# HWLOC_LIBDIR - Where to find the library files
|
|
28
|
+# The module can also look for the following environment variables if paths
|
|
29
|
+# are not given as cmake variable: HWLOC_DIR, HWLOC_INCDIR, HWLOC_LIBDIR
