CMake find_package(wxWidgets) fails with vcpkg wxwidgets package

[LegalizeAdulthood]

Describe the bug
vcpkg builds and installs wxwidgets but CMake find_package can't locate wxwidgets from vcpkg package

Environment

• OS: Windows
• Compiler: VS 2019

To Reproduce
Steps to reproduce the behavior:

1. Unpack attached zip example-wxwidgets.zip
2. Run CMake with the vcpkg toolchain file to generate a build
3. CMake fails at configure time attempting to find wxwidgets because setup.h is in the wrong directory (see my comments on this related issue and this pull request)

Expected behavior
The package created by vcpkg should be compatible with existing CMake wxWidgets find modules.

Failure logs

• See attached zip

Additional context
n/a

Since this fails at configure time, a regression test case would simply build vcpkg and attempt to configure the example in the ZIP.
The example is 'Hello World!" from the wxwidgets.org site. If the configure step in CMake succeeds, then we successfully found wxWidgets via find_package from the package created by vcpkg.

[LegalizeAdulthood]

OK, it seems that wxWidgets find modules expect a directory layout that is similar to what you get after a build of wxWidgets and vcpkg is re-organizing the entire directory tree, confusing the find modules.

I don't think vcpkg should be reorganizing the directories into a form not recognized by the find modules in CMake.

Hi @LegalizeAdulthood

Thanks for posting this issue.

It's duplicated to #4756, which will be fixed via PR #13361.

Let's move the attention to #4756.
