Unable to compile CGAL example Triangulation_2

I have installed CGAL with vcpkg. Also installed Qt5 with vcpgk. Then I have dowloaded CGAL-5.0-examples and ran cmake-gui ... It did without errors. Qt5 variables appeared to point to some places inside vcpkg. Unfortunately, after sln is genereted and I am opening it, I can't build it:

Severity    Code    Description Project File    Line    Suppression State   Suppression State

Why is it trying to open cpp files from build directory, although source directory is one level up?

You need to install cgal[qt] for examples that use Qt5 : vcpkg install cgal[qt] This contains specific headers for most 3D examples and demos used by CGAL.

Also there is a specificity when using vcpkg with cmake, because the default behavior for Optional Platform is x64 in cmake, but x86 in vcpkg. it means that if you leave it empty, everything that comes from outside vcpkg will be x64, and everything inside vcpkg x86, and you will run into warnings, link errors and probably some build errors too. This page explains the steps to configure and build an example of CGAL with vcpg.
