[spindensity]

Describe the bug

Tools (qmlscene, designer, etc) in vcpkg:x64-windows build crashes.

Environment

• OS: Win10 1903
• MSVC 2017 15.9.16

To Reproduce

Steps to reproduce the behavior:

1. vcpkg install qt5:x64-windows;
2. Run command %VCPKG_ROOT%\installed\x64-windows\tools\qt5\bin\qmlscene.exe --help;, nothing outputs, the program just crashes silently;
3. Open %VCPKG_ROOT%\installed\x64-windows\tools\qt5\bin directory in file explorer and double click designer.exe, the program crashes due to missing dlls.

Expected behavior

Tools work like them in the official distribution.

That is a generell problem with how qt is integrated into vcpkg and how vcpkg handles packages. Sry, there is nothing which could be done here to solve the problem.
As far as I remember qmlscene is build by qt5-declarative so you have to use the version in %VCPKG_ROOT%\installed\x64-windows\tools\qt5-declarative\bin\qmlscene.exe. Alternatively, you could add the path %VCPKG_ROOT%\installed\x64-windows\bin to your PATH variable or build qt5 static.
