| # - 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 | ||
