clangd does not work correctly with CMake INTERFACE libraries

• interface libraries don't appear in the C++ Code Model Inspector.
• clangd doesn't seem to get the compiler parameters, resulting in errors in the standard library headers and warnings like -Wc++17-extensions in my code (even though I compile with -std=c++20 or /std:c++latest).

Can be easily reproduced with my project: https://github.com/absurdworlds/awlib. For example "error: No member named basic_string_view in namespace std" in the file "\types\include\aw\types\string_view.h".
I am using clangd shipped with the Qt Creator.
