aliDoctor does not report on all dependencies

[matthiasrichter]

The o2codechecker.sh recipe specifies clang and CMake as dependencies, however aliDoctor --defaults o2 o2codechecker reports only about CMake

SUCCESS: Package CMake will be picked up from the system.
==> The following packages will be picked up from the system:
    
    - CMake
    If this is not you want, you have to uninstall / unload them.

Is this a feature or bug?I noticed a difference how o2codechecker.sh specifies the dependencies

requires:
  - Clang
build_requires:
  - CMake

I can confirm this. Had similar behaviour on current master (a59506f) when running aliDoctor --defaults o2 FairRoot. It was missing ROOT and DDS in my case:

$ aliDoctor --defaults o2 FairRoot
(...)
==> The following packages will be picked up from the system:
    
    - Python-modules
    - FreeType
    - Python
    - GCC-Toolchain
    - yaml-cpp
    - autotools
    
    If this is not you want, you have to uninstall / unload them.

==> The following packages will be built by aliBuild because they couldn't be picked up from the system:
    
    - CMake
    - protobuf
    - nanomsg
    - ZeroMQ
    - boost
    - GSL
    
    This is not a real issue, but it might take longer the first time you invoke aliBuild.
    Look at the error messages above to get hints on what packages you need to install separately.
