#include shown as not found (wiggly red lines) but code compiles

[hros]

I've created a cmake cpp library project with a vcpkg.json file (manifest mode) which downloads cpprestsdk with its dependencies

At the top of the autogenerated source file I've add two include files for cpprestsdk:

#include <iostream>

#include <cpprest/json.h>
#include <cpprest/http_listener.h>

void say_hello(){
    std::cout << "Hello, from FastAPIcpp - lib!\n";
}

the project compiles successfully, but vs code show an error for the first include (json.h): file not found
interestingly, if I switch the order of the two includes:

#include <cpprest/http_listener.h>
#include <cpprest/json.h>

the file not found error is displayed again for the first file, this time: http_listener.h

note that CMakeLists.txt has package dependency command: find_package(cpprestsdk CONFIG REQUIRED) and the whole project is configured and built successfully
moreover, the "missing" include files are present in build/vcpkg_installed/x64-linux/include/cpprest/

is there any vs code setting that has to be set for the extension to add the vcpkg include directories?

@hros The "file not found" error is not from our extension. Do you have another extension installed that could generating that? It may be from the "C/C++ Clang Command Adapter extension" extension, so you should disable that one.

thanks @sean-mcmanus
I noticed that the error is from "clang-tidy(clang-diagnostic-error)"
I searched the web for this issue and found this github issue, which you answered.... Perhaps you'll be able to help me with a similar issue.
