# a. as an environment variable, e.g.
# $ export PETSC_DIR=/usr/lib/petscdir/3.6.2/x86_64-linux-gnu-real
# b. or as an CMake variable, e.g.
# $ cmake .. -DPETSC_DIR==/usr/lib/petscdir/3.6.2/x86_64-linux-gnu-real
# 2. or by using the pkg-config mechanism, e.g.
# $ export PKG_CONFIG_PATH=/usr/lib/petscdir/3.6.2/x86_64-linux-gnu-real/lib/pkgconfig:$PKG_CONFIG_PATH
