C Static Analysers: setting up to automatically include all files that the IDE/compiler knows about

Do I have to manually tell the static analyser which files to include in the analysis? I'm using a NetBeans-based IDE (MPLAB X) to program an embedded system in C (with the XC8 compiler). It is very easy to build the project, and when I add .c or .h…
