| ## Per project subproject options rewrite |
| |
| You can now define per-subproject values for all shared configuration |
| options. As an example you might want to enable optimizations on only |
| one subproject: |
| |
| meson configure -Dnumbercruncher:optimization=3 |
| |
| Subproject specific values can be removed with -U |
| |
| meson configure -Unumbercruncher:optimization |
| |
| This is a major change in how options are handled, and the |
| implementation will evolve over the next few releases of Meson. If |
| this change causes an error in your builds, please [report an issue on |
| GitHub](https://github.com/mesonbuild/meson/issues/new). |
| |
| We have tried to keep backwards compatibility as much as possible, but |
| this may lead to some build breakage. |
