You can set the CXX environment variable, CMake should always pick those up.

You see, cc="mpcc_r" is passed to cmake, but no cxx. Cmake tries to find cxx but failed. <blockquote> Hi, I try to install petsc-dev on AIX/PPC cluster. I'd like to use xlc, however, there is a dead gcc/g++ installed in /usr/bin. Since I am not the administrator, I can't do anything to remove/update it. Specify the compilers using --with-cc --with-cxx --with-fc. I suggest you specify the MPI compiler wrappers for this machine.
