Hi, this PR adds two feature flags to Blaze to allow for a minimal 'core' installation: 1. `lapack`: LAPACK/BLAS is currently a default dependency, but its only required for certain matrix operations and `BLAZE_BLAS_MODE` which is off by default. See [CMakeLists.txt#L65-L75](3156507a4b/CMakeLists.txt (lines-65):75). 2. `openmp`: The absence of this flag actually disables SMP support entirely, so it might be better to just use `smp` instead. Thoughts? I used `openmp` for consistency with the existing port which explicitly sets the threading library via `BLAZE_SMP_THREADS=OpenMP`. In any case, Blaze defaults to OpenMP and removes `BLAZE_SMP_THREADS` from cache when `BLAZE_SHARED_MEMORY_PARALLELIZATION` is turned off. See [CMakeLists.txt#L297-L304](3156507a4b/CMakeLists.txt (lines-297):304). Both of these are still set as default features to ensure compatibility, though I think the default LAPACK REQUIRED as a reminder to package maintainers might be a bit excessive! If you're using LAPACK, you probably aren't relying on Blaze to import it for you. That's probably more of a discussion for upstream in any case. - [x] Changes comply with the [maintainer guide](https://github.com/microsoft/vcpkg-docs/blob/main/vcpkg/contributing/maintainer-guide.md). - [ ] ~~SHA512s are updated for each updated download.~~ - [ ] ~~The "supports" clause reflects platforms that may be fixed by this new version.~~ - [ ] ~~Any fixed [CI baseline](https://github.com/microsoft/vcpkg/blob/master/scripts/ci.baseline.txt) entries are removed from that file.~~ - [ ] ~~Any patches that are no longer applied are deleted from the port's directory.~~ - [x] The version database is fixed by rerunning `./vcpkg x-add-version --all` and committing the result. - [x] Only one version is added to each modified port's versions file.
