<pre>
    After generating the documentation, `clang-doc` generates some references that link to the definition and implementation of each function/method. But, it generates an implementation reference in this way
```html
<h3 id="180C359AB8E98A663762001FF59A0FA5F0D9240B">add</h3>
<p>public int add(int a, int b)</p>
<p>
  Defined at line 
  <a href="Inputs/basic-project/src/Calculator.cpp#3">3</a>
   of file 
  <a href="Inputs/basic-project/src/Calculator.cpp">Calculator.cpp</a>
</p>
```
So, when hosting it using an HTTP server or directly from the browser and clicking on the link, the browser will redirect it as a child for the current path (`docs/GlobalNamespace/` in our case), and this path doesn't refer to the correct path of the definition/implementation file.

## Possible Solution
I think by converting this path into the absolute path from the root. The output will be similar to this:

```html
<h3 id="180C359AB8E98A663762001FF59A0FA5F0D9240B">add</h3>
<p>public int add(int a, int b)</p>
<p>
  Defined at line 
  <a href="/home/USER/<parent-directory>/Inputs/basic-project/src/Calculator.cpp#3">3</a>
 of file 
  <a href="/home/USER/<parent-directory>/Inputs/basic-project/src/Calculator.cpp">Calculator.cpp</a>
</p>
```
