You could look at PETSc install instructions and examples https://petsc.org/release/install/install/#common-example-usages

Assuming a linux box with  cuda at /usr/local/cuda, mpicc etc in PATH, and have system blas/lapack installed, the following build process should work

./configure --with-cuda=1 --with-petsc4py && make && make check
