[yocto] Extracting PV & PR from Makefile at compilation time.

[Bipnesh, Abhinav (Abhinav)]

One quick way would be to use environment variables in both places. So you can export them before starting a build.

I have a Makefile with this header

major = 1
minor = 0
patch = 10
release = -beta

Which compilates someting like libmylib.so.1.0.10-beta shared object.
On recipe I duplicate this information:
PV="1.0.10"
PR="-beta"

Is there anyway to grab that information from Makefile and setting PV & PR according to it? At compilation time? So that I only have to change at one place?

bitbake wants to know pv/pr at parse time, long before the sources have been fetched and unpacked.
