Describe the bug

• OS and Version:
• VS Code Version: 1.31.1
• C/C++ Extension Version: 0.21
• Other extensions you installed (and if the issue persists after disabling them):
• A clear and concise description of what the bug is.

To Reproduce

1. I add two folders to a new workspace, one folder is "cpps" and another one is "headers"
2. In "apps" folder there is a cpp file called "cpp_test.cpp" and in "headers" folder there are two files, "header_test.h" and "header_test.cpp".
3. code as following:

cpp_test.cpp(in cpps folder)
#include "../headers/headers_test.h"
int cpps_test()
{
ClassA *obj = new ClassA();
obj->test(); //"go to definition" on function "test" will go to declaration instead of def.
}

headers_test.h(in headers folder)
class ClassA {
public:
ClassA(){}
int test();
};

"headers_test.cpp(in headers folder)
#include "test.h"
ClassA::test(){
int mm = 0;
}

This is a bug? Are there some ways to resolve this issue?
