FindOpenACC

New in version 3.10.

Detect OpenACC support by the compiler.

This module can be used to detect OpenACC support in a compiler. If the compiler supports OpenACC, the flags required to compile with OpenACC support are returned in variables for the different languages. Currently, only PGI, GNU and Cray compilers are supported.

Variables

This module will set the following variables per language in your project, where <lang> is one of C, CXX, or Fortran:

OpenACC_<lang>_FOUND

Variable indicating if OpenACC support for <lang> was detected.

OpenACC_<lang>_FLAGS

OpenACC compiler flags for <lang>, separated by spaces.

OpenACC_<lang>_OPTIONS

OpenACC compiler flags for <lang>, as a list. Suitable for usage with target_compile_options or target_link_options.

Additionally, the module provides IMPORTED targets:

OpenACC::OpenACC_<lang>

Target for using OpenACC from <lang>.

The module will also try to provide the OpenACC version variables:

OpenACC_<lang>_SPEC_DATE

Date of the OpenACC specification implemented by the <lang> compiler.

OpenACC_<lang>_VERSION_MAJOR

Major version of OpenACC implemented by the <lang> compiler.

OpenACC_<lang>_VERSION_MINOR

Minor version of OpenACC implemented by the <lang> compiler.

OpenACC_<lang>_VERSION

OpenACC version implemented by the <lang> compiler.

The specification date is formatted as given in the OpenACC standard: yyyymm where yyyy and mm represents the year and month of the OpenACC specification implemented by the <lang> compiler.

Input Variables

OpenACC_ACCEL_TARGET=<target> If set, will the correct target accelerator flag set to the <target> will be returned with OpenACC_<lang>_FLAGS.
