Unable to compile due to Debian not providing include/linux/broadcom

Tried to ./compile.sh, however the broadcom include folder doesn't seem to be provided (on Raspbian with sid repos) in the linux-headers-6.6.31+rpt-common-rpi package, even though apt-file search lists it as one of the packages that provides that folder.

Upon manual download and inspection of that package, linux/broadcom/ is nowhere to be found.

any way to solve this?

Start with compile.sh and reproduce the failure using the reported linux-headers-6.6.31+rpt-common-rpi package on Raspbian with sid repositories. Compare the include/linux/broadcom path expected by the build with the package contents; done means establishing a supported dependency or documenting a reproducible resolution.
