It looks like the linker found the 64-bit version of the library 
libGL.so but decided it was incompatible. That suggests that the code to 
which it is being linked (ParaView) is 32-bit. It might be that your 
compiler generates 32-bit code by default and needs a command-line flag 
to generate 64-bit code.

Figure out what that flag should be, tell cmake to use it, regenerate 
the make files and recompile. Add the new flag by editing the file 
CMakeCXXCompiler.cmake in directory CMakeFiles under the binary 
directory where you are building paraview.

I'm not sure where to edit that file; you may have to experiment. It 
looks like the file sets a variable named CMAKE_CXX_COMPILER_ARG1 to a 
string so you could put the flag there. The book on cmake, or perhaps 
the web site, might be able to provide better guidance.
