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.

* [GraphicsMagick] bug-fix: image files won't load
GM (GraphicsMagick) was failing to load image files, notably PNG or JPEG
images, as it was being compiled with support for 'GraphicsMagick
Modules'. These are files with names specific to GM, and of the format,
'IM_*.dll'. vcpkg's install process was not setting these up. This
patch makes sure that when GM is built, it embed's GM's own
image-loading code into graphicsmagick.dll.
* [vcpkg_extract_source_archive_ex] Add PATCHES argument
* [openmesh] Use direct download instead of gitlab
* [blaze] Use PATCHES argument
* [graphicsmagick] Use vcpkg_extract_source_archive_ex
