Analysis from CMake file

[rogerdubbs]

As a CMake user, I don't want to have to create another project configuration file to specify my product structure. cppdep should be able to use CMake to gather this information. This might be done with a build generator or it might be done via APIs that I understand CMake is making available for IDEs.

@rogerdubbs I am so much with you on this, you wouldn't believe it :).
Trying to perform analysis with the same settings file on several machines is disaster right now.

However, I should say that I don't like configuration file at all. What I want is cppdep deduce all system dependencies or is supplied on command line, e.g. "-I /usr/include/boost".
Only thing you would need is the directory of your project;
that is, simple command "cppdep myproject" should get the job done.

@rogerdubbs Thanks for putting this issue.

CMake could tell about project structure via "file-api", and some physical deps could be extracted from "Compile Database" files (compile_commands.json, enabled via CMAKE_EXPORT_COMPILE_COMMANDS=ON )
