I am using the CS+ integrated development environment.
I am trying to create a file that I want to let a source file include. Do I need to specify the option settings of the build tool?
You need to set the include file path in the properties of the build tool.
When you register (*) a file with an extension to be recognized as an include file in a project, a path to the file is automatically set for the include file path in the properties of the build tool.
For details about how to add a file to a project, see this site.
