A prototype for a standalone code checker for the AliceO2 project

It offers:

• code checks based on clang-tidy and existing components
• standalone CMake infrastructure for compilation outside of llvm/clang source tree

• llvm + clang + clang extra tools (release 3_9) required
  • (recommended to use alibuild build clang which will give you the right version)
• build using cmake -DLLVM_DIR=PATH_TO_LLVM_CMAKE_CONFIG -DClang_DIR=PATH_TO_CLANG_CONFIG

In the build directory of AliceO2 (containing the CMake compilations database in form of compile_command.json), run

run_O2CodeChecker.py -clang-tidy-binary `which O2codecheck` -checks=*,alice*
