Check prerequisites
The check should cover all dependencies needed for the extension to
be built and run. The method can do the following:
- return a false value: the extension will be built
- return a true value: the extension will be skipped. This is useful
for optional extensions
- raise an exception. This is useful for mandatory extensions
If the check result is cacheable (during the setup run), override
`cached_check_prerequisites` instead.

`build` : `BuildExt`
