How to recompile GROMACS with GPU support?

GROMACS version: 2020.1-Ubuntu-2020.1-1
GROMACS modification: No

 gmx mdrun -v -deffnm md_0_10 -nb gpu

“Nonbonded interactions on the GPU were requested with -nb gpu, but the GROMACS
binary has been built without GPU support. Either run without selecting GPU
options, or recompile GROMACS with GPU support enabled”

I installed GROMACS without GPU but now i want to support without removing GROMACS from the system… How??
I use Ubuntu Terminal [Ubuntu 20.04.4 LTS] on windows 10.

Don’t use pre-compiled software from a package manager; you are sacrificing performance by doing so. Compile from source; instructions are available in the online manual.
