Hello Denis, Thanks for your reply.
Candi looks like a good option to use to install all the libraries. However, I also need mumps which Petsc installs for me when I install libraries separately. I looked at the cdf file. It says that it installs Petsc, trilinos, slepc and other libraries. Can candi install mumps along with petsc ? Also, I faced a problem using examples after installing dealii. I am making a new post for that as that is not related this issue. If I am able to solve this error, I will post the solution here.
