CMake work for VATES-ParaView

[Michael Reuter]

The CMake build system for the VATES-ParaView code needs a bit of work done to it. Some of the things to be done:

• Remove duplicate find_package calls
• Use standard CMake variables from ParaView
• Trap GMock usage behind flags
• Create new location for plugin libraries
• Correct environment to get a Jenkins build going
• Add installation commands
