Re: cmakelists.txt fot C++ IDE

[Marcus Müller]

Hi Ali,

since CMake is the default build system we use both for our OOT templates (as used by 
gr_modtool) and by the C++ code generated throug GRC, I'd say:

just use the existing work as template.

What you're doing here is mixing modern CMake, i.e. a config/target-based method of 
defining the compiler and linker properties of your compilation units, with manual 
"include_directories" things. Probably not a great idea! If you compare that with what 
`gr_modtool` generates in its lib/CMakeLists.txt, you'll find how we'd, as a project, 
would recommend you do it.

Best,
Marcus
