Including a single header file

Hi there,

context (skip if you what):

"I'm working with the microcontroller TMS320F28386D, and i have a project with multiple cores, CPU1, CPU2 and CortexM, resulting in 3 projects, the CPUx cores have the sysconfig tool to configure pin mux and generates a header file with name "board.h" automatically, i want to import this header file to CortexM project without import others automatically generated headers in the same directory."

Problem:

Is there any way to include only a header file from a extern directory with multiple header files to a project? or automatically copy this file before building the project? or any other solution using a system project?

Thanks for your guidance,

Ramon,
