You are specifying libraries that do not exist. Do not do this. You can use
the PETSc Makefiles to build
this, as described in the manual:


https://urldefense.us/v3/__https://petsc.org/main/manual/getting_started/*sec-writing-application-codes__;Iw!!G_uCfscf7eWS!dR3K5-koJJZxrylQZPi1wyTnMeuWa7qeAM46G7OwoWYcDHB_OHBNiTMPGfh-JeAxS5XzHp7hBitgk6cOgnFL$ 

under the section "For adding PETSc to an existing application"

  THanks,

     Matt
