# FindOpenMP
|
|
# ----------
|
|
#
|
|
# Finds OpenMP support
|
|
#
|
|
# This module can be used to detect OpenMP support in a compiler. If
|
|
# the compiler supports OpenMP, the flags required to compile with
|
|
# OpenMP support are returned in variables for the different languages.
|
|
# The variables may be empty if the compiler does not need a special
|
|
# flag to support OpenMP.
|
|
#
|
|
# Variables
|
|
# ^^^^^^^^^
|
|
#
|
|
# This module will set the following variables per language in your
|
|
# project, where ``<lang>`` is one of C, CXX, or Fortran:
|
|
#
|
|
# ``OpenMP_<lang>_FOUND``
|
|
# Variable indicating if OpenMP support for ``<lang>`` was detected.
|
|
# ``OpenMP_<lang>_FLAGS``
|
|
# OpenMP compiler flags for ``<lang>``, separated by spaces.
|
|
#
|
|
# For linking with OpenMP code written in ``<lang>``, the following
|
|
# variables are provided:
|
|
#
|
|
# ``OpenMP_<lang>_LIB_NAMES``
|
|
# :ref:`;-list <CMake Language Lists>` of libraries for OpenMP programs for ``<lang>``.
|
|
# ``OpenMP_<libname>_LIBRARY``
|
|
# Location of the individual libraries needed for OpenMP support in ``<lang>``.
|
|
# ``OpenMP_<lang>_LIBRARIES``
|
|
# A list of libraries needed to link with OpenMP code written in ``<lang>``.
|
|
#
|
|
# Additionally, the module provides :prop_tgt:`IMPORTED` targets:
|
|
#
|
|
# ``OpenMP::OpenMP_<lang>``
|
|
# Target for using OpenMP from ``<lang>``.
|
|
#
|
|
# Specifically for Fortran, the module sets the following variables:
|
|
#
|
|
# ``OpenMP_Fortran_HAVE_OMPLIB_HEADER``
|
|
# Boolean indicating if OpenMP is accessible through ``omp_lib.h``.
|
|
# ``OpenMP_Fortran_HAVE_OMPLIB_MODULE``
|
|
# Boolean indicating if OpenMP is accessible through the ``omp_lib`` Fortran module.
|
|
#
|
|
# The module will also try to provide the OpenMP version variables:
|
|
#
|
|
# ``OpenMP_<lang>_SPEC_DATE``
|
|
# Date of the OpenMP specification implemented by the ``<lang>`` compiler.
|
|
# ``OpenMP_<lang>_VERSION_MAJOR``
|
|
# Major version of OpenMP implemented by the ``<lang>`` compiler.
|
|
# ``OpenMP_<lang>_VERSION_MINOR``
|
|
# Minor version of OpenMP implemented by the ``<lang>`` compiler.
|
|
# ``OpenMP_<lang>_VERSION``
|
|
# OpenMP version implemented by the ``<lang>`` compiler.
|
|
#
|
|
# The specification date is formatted as given in the OpenMP standard:
|
|
# ``yyyymm`` where ``yyyy`` and ``mm`` represents the year and month of
|
|
# the OpenMP specification implemented by the ``<lang>`` compiler.
|
|
#
|
|
# Backward Compatibility
|
|
# ^^^^^^^^^^^^^^^^^^^^^^
|
|
#
|
|
# For backward compatibility with older versions of FindOpenMP, these
|
|
# variables are set, but deprecated::
|
|
#
|
|
# OpenMP_FOUND
|
|
#
|
|
# In new projects, please use the ``OpenMP_<lang>_XXX`` equivalents.
