[petsc-users] Doubt about distribution of PETSc in a CMake project

[Sebastian Gutierrez]

Good morning Satish,

I tried this solution and I could effectively link the libraries to the
executable in a new machine. Nonetheless, I am having now a new problem
when I am trying to execute my program on the new machine. Since the new
machine does not have petsc nor mpi installed, the program throws me this
error message (see image attached), but I do not want the final users to
install mpi their own. Is it any solution to this issue? Can you help me,
please?
 I am looking forward to hearing from you.

Best regards,

Sebastian
