| <p>Functions to help assemble a standalone Qt4 executable.</p> |
| <p>A collection of CMake utility functions useful for deploying Qt4 |

| and can be drag-and-drop copied to another machine as long as all of |
| the system libraries are compatible.</p> |
| <p><executable> should point to the executable to be fixed-up.</p> |
| <p><qtplugins> should contain a list of the names or paths of any Qt |
| plugins to be installed.</p> |
| <p><libs> will be passed to BundleUtilities and should be a list of any |

| fixed-up.</p> |

| directories to be searched to find library dependencies.</p> |
| <p><plugins_dir> allows an custom plugins directory to be used.</p> |
| <p><request_qt_conf> will force a qt.conf file to be written even if not |
| needed.</p> |
