How to add top level folder for C/C++ builds in eclipse

[ngoliNI]

When I add a folder in 'Includes', the .h files under its subfolders are not getting picked up.
But when added the exact file path for a header file, it works.

Can anyone suggest on how to add the top-level directory so that the build path searches its respective subfolders also?

Not sure I fully follow the question. A screenshot of your setting may help clarify.

Here is what I would setup to include files in my project:

The bit of magic is making your include directory in the setting something like "${workspace_loc:/${ProjName}/src/myincludes}"

Thank you for the response. I am calling some MATLAB header files in a program. And that header file has multiple dependencies. Adding each of the header file paths in the 'Includes' is tedious as there are multiple paths. Is there any way, if I add the top-level directory, the paths from their subdirectories get picked up without manually adding all of them as all of the header paths are in different sub-directories?

Thanks for clarifying.

No, there is no way I know of to do that.

Using some shell and makefile tricks could potentially enable such a flow, but as you are using the Eclipse CDT internal builder, even those aren't an option.
