How to use makefile to copy the library and inc file of dependencies after built?

[LuoSYLuo]

I am the new developer. one thing that I want to do is copy project's library file and header file of the library dependencies:
And I need to complete this build by makefile(GNU Makefile)

ex:
-ProjectA
--inc
--ProjectA_API.h
--ProjectA_Type.h
--lib
--Release
--ProjectA.a

-Main
--bin
--src
Makefile

How can I complete this build project task by makfile to copy the library dependencies?
does it use many make variables(ex: PROJECRT_NAME, PROJECT_HOME) or makefile.include to write the makefile?

Becasue I can use post-build and write the batch file to copy all project's library file and header file, it will copy the library not included in this project.

ex:
for /R C:\usr\xtensa\AAA %%f in (*.a) do copy "%%f" C:\usr\xtensa\AAA\

You can add a makefile.targets file in the root of your project with any makefile targets you want. For example, if you want something copied before the final link and your project is called simple adding a target like this to the makefile.targets would probably work:

simple: ../path/to/file
	cp $< .
