Describe the bug
Opencascade 7.5.0 builds (as windows-x64-static) without any errors.
However Visual Studio 2019 can not find the header files for Opencascade itself whenever a header from said library is included.
For example when I want to #include <opencascade/gp.hxx>, Visual Studio 2019 says:
1>C:\Sys\vcpkg\installed\x64-windows-static\include\opencascade\gp.hxx(20,10): fatal error C1083: Cannot open include file: 'Standard.hxx': No such file or directory

Environment

• OS: Windows 10
• Compiler: Microsoft (R) C/C++ Optimizing Compiler Version 19.28.29337 for x86

To Reproduce
Steps to reproduce the behavior:

1. ./vcpkg install opencascade.
2. Create empty project (C++) in Visual Studio 2019.
3. Create a .cpp file and #include <opencascade/gp.hxx>.
4. See error: 1>C:\Sys\vcpkg\installed\x64-windows-static\include\opencascade\gp.hxx(20,10): fatal error C1083: Cannot open include file: 'Standard.hxx': No such file or directory.
