The content of the folder has those sub-folders, sbin, root, lib, etc.
Those sub-folders contains files such as executable binaries, config
files, kernel modules, .so files ...
All these files are actually built from the source code of a specific
WiFi driver,
what I want to do is installing all pre-built binaries/files into
corresponding locations in rootfs.

Yes, all files are installed in a package.

This line is removed.

Yes, got some QA-warnings when building so I keep this.

No, header files aren't in the package.
I checked the driver source code and many files include kernel headers
like this "#include <linux/xxx.h>" , is this what you meant by dependency on
kernel headers?
IMAGE_FEATURES was not used in the recipe file.

I add this line and rebuild but the result seems unchanged.
the .debug folders are located in
${WORKDIR}/package
${WORKDIR}/package-split/<package name> - dbg
