<p class="MsoNormal"><span style="font-size:10pt;color:rgb(64,64,64)">We want to create a tool (in C# .NET, EXE) which invokes the clang tool (C++, DLL). While implementing we realized that the CommonOptionsParser only expects the call to the Clang tool to be in
the form of command line options. Is there a way around this issue that someone has encountered earlier?

<p class="MsoNormal"><span style="font-size:10pt;color:rgb(64,64,64)">On the other hand, if I pass the c code as a string buffer to the tooling, the included .h files are not recognized by clang tooling. So somehow Common Options Parser was the choice.<u></u><u></u></span></p>
