Vcpkg: [graphicsmagick] Also build Magick++

[leha-bot]

Is your feature request related to a problem? Please describe.
Currently vcpkg compiles GraphicsMagick and properly installs its headers and Magick++ headers, but doesn't compile Magick++ itself.

Proposed solution
Build Magick++ as a feature of package GraphicsMagick

Describe alternatives you've considered
The alternatives are dark: either use (partially broken) Conan recipe, or compile it yourself (which is very painful as upstream library heavy sits on Autotools or on "VisualMagick" C++ tool)

Additional context
Right now simple example with Magick++ doesn't compile:

This screen is from my test project https://github.com/leha-bot/kind-of-magick . Garbled text tells us that there are unresolved external symbols which available in Magick++ lib. Also this garbled text have been reported as a bug in msbuild by me.

Thank you for your work and project!

Port author here. Magick++ is built and included in the port. I manually test the build with a Magick++ based application. See attached.

@josuegomes So, that's expected?

[josuegomes]

OP's problem is something else. It's likely a static/dynamic mismatch. Since Magick++ is already included this issue can be closed.

@josuegomes Thanks for reply.

Hi @leha-bot, I cannot reproduce your problem on my computer using the project file you provided.
So, please provide the Visual Studio version and the triplet you are using.

Thanks.
