[armadillo]Fix usage error.

[JackBoosY]

Add dependent port openblas.
Add vcpkg_configure_cmake options.

• Fix share path error in linux.
• Add dependent port clapack.

Relate: #5804.

BTW: Why is the macro VCPKG_CMAKE_SYSTEM_NAME is empty when running portfile.cmake?

mmm... this is really strange, since it is the correct way to understand the system on which you are running... (as I was saying in the review)

[JackBoosY]

@cenit Yeah, I prefer to use VCPKG_CMAKE_SYSTEM_NAME to distinguish between different platforms.
Sometimes it works, sometimes it's empty.

[cenit]

when it's empty you are on Windows desktop. It just depends on your triplet :)

@cenit Clapack did not generate config.cmake file. So if I modify CMakeLists.txt and add find_package(clapack CONFIG REQUIRED) then port clapack will not be imported correctly.
And I found... we can just add clapack dependencies to solve this problem.

that's a problem I am trying to solve in #6371

[JackBoosY]

@cenit In fact, if there is no port-config.cmake file, we can use find_library to solve the problem of finding the debug/release library path and use target_link_libraries to use the dependency library.

[cenit]

That’s exactly what I did in that PR :)

This issue has been fixed in #6371.
