[cfe-dev] LibTooling CMake Error

[Mohammad Adil]

Also, I've trying to build the simple syntax checker tool and run it. I
create a .json file in my build directory and build the tool. The tool
builds fine. But when I call the tool using

./simple-tool test.cpp

or any other arguments, it gives an error saying

skipping ...
Command Line not found

What is the problem here? How can it be rectified?

Regards,
Adil
