| # |
| # BlueGeneP-dynamic For dynamically linked builds |
| # BlueGeneP-static For statically linked builds |

| # For BGP builds, we're cross compiling, but we don't want to re-root things |
| # (e.g. with CMAKE_FIND_ROOT_PATH) because users may have libraries anywhere on |
| # the shared filesystems, and this may lie outside the root. Instead, we set the |
| # system directories so that the various system BGP CNK library locations are |
| # searched first. This is not the clearest thing in the world, given IBM's driver |
| # layout, but this should cover all the standard ones. |
