[petsc-users] cmake METIS problem

[Gong Ding]

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.  

The cmake configure file for metis tries to find c++ compiler, and reported error with that g++.

Error running configure on METIS: Could not execute "cd /gpfs1/cogenda/cogenda/packages/petsc-dev/externalpackages/metis-5.0.2 && make distclean && make config prefix=/gpfs1/cogenda/cogenda/packages/petsc-dev/IBM-XLCPP cc="mpcc_r" doubleprecision=1":

I think the testing for c++ compiler can be removed here?
