[cfe-dev] LibTooling CMake Error

[Mohammad Adil]

I've checked out the extra tools repository at the correct place and I have
built clang again, with the CLANG_BUILD_EXAMPLES variable set to true in
cmake. I am still getting the same error. What can possibly be wrong? Can
you please provide all the steps required to make this command work.
     The two cmake files you mentioned are both related to libclang. I am
using Libtooling. How do I adapt them to build the FrontEndAction example
given in the docs.
