The PostgreSQL library is located with this script:
   VTK/CMake/FindPOSTGRES.cmake
and a call to LINK_LIBRARIES is made here:
   VTK/IO/CMakeLists.txt
if PostgreSQL is turned on. Interestingly, LINK_LIBRARIES is used
instead of TARGET_LINK_LIBRARIES. Perhaps that should be changed to
TARGET_LINK_LIBRARIES (both for PostgreSQL and MySQL)? Also, perhaps on
MacOS X there are some dependent libraries required that are not being
located? The FindPOSTGRES.cmake script doesn't look for any, so if zlib
or any ssl libraries are required that might cause trouble in the case
where libpq is static.
