As expected; the options specified in a project file apply to sources
included in the project file. That way, you can have several project
files, each with a list of sources and options.

ADA_INCLUDE_PATH is a hold-over from pre-project-file times.

Feature.

Create a project file for the sources now in ADA_INCLUDE_PATH, and
'with' that project file from your main project file.

If you want the same options (sounds like you do), create an 'options'
project file that just defines some variables, and use those variables
in the other project files.
