the error does not show up

When I enter this piece of code, IntelliSense correctly highlights the error in "co ut" with a red squiggly line:

#include <iostream>    
using namespace std;
int main()
{
    co ut <<"hello world"<<endl;
    return 0; 
}

However, when I add the Conan package gtest, the error does not show up:

#include <iostream>     
#include <gtest/gtest.h>
using namespace std;
int main()
{
    co ut <<"hello world"<<endl;
    return 0; 
}

This happens even though my "C_Cpp.errorSquiggles" setting is set to "enabled". Why is this?

in c_cpp_properties.json

"includePath": [
                "/home/sadfl/.conan/data/**",
                //"/usr/include/**",           when I remove this line,the problem was solved,I don't know why
                "${workspaceFolder}/dms_workflow/**"
            ],

Including all folders beneath /usr/include usually breaks the configuration. I thought we had code to automatically remove that mistake from peoples' configurations, but perhaps there is some scenario we overlooked. Can you add that line back in to your configuration, open the source file again, run the C/C++: Log Diagnostics command, and then share that output with us?
