| # By default, there is no easy way in CMake to set the value of a cache |
| # variable without reinitialising it, which involves resetting its |
| # associated help string. This is particularly annoying for CMake options |
| # where they need to programmatically updated. |
| # |
| # This function automates this process by getting the current help string |
| # for the cache variable to update, then reinitialising it with the new |
| # value, but with the original help string. |
