When I try to compile my project in MCUxpresso I get this message, even my file is present.
I have added two virtual folders and have included linked source files from another folder using drag drop method.
One folder is "source/BSP" and another is "source/COMMON_UTILS".
When a header file from BSP is included in some header in COMMON_UTILS it shows this error message. The headers are getting compiled when any file in the "source" folder includes it.
I am attaching screen shot of settings.
