make files paths : /home/ovsa/krupa/Makefile2/tool
/home/ovsa/krupa/Makefile2/runtime
/home/ovsa/krupa/Makefile2/License
iam running the make in :: make -C ./krupa/Makefile2/License all
Giving below error:
make: Entering directory ‘/home/ovsa/krupakar/Makefile2/License’
mkdir -p /home/ovsa/../License/lib /home/ovsa/../License/bin /home/ovsa/../License/src/lib
mkdir: cannot create directory ‘/home/ovsa/../License’: Permission denied

make: Leaving directory ‘/home/ovsa/krupakar/Makefile2/License’
It is not taking the exact path of the makefile, It is creating the directory in /home
