| <p>Detect OpenACC support by the compiler.</p> |
| <p>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 NVHPC, PGI, GNU and Cray compilers are supported.</p> |
