[vtkusers] QVTKWidget linux link error "relocation R_X86_64_32S against `a local symbol' can not be used when making a shared object; "

[Karthik Krishnan]

Add something along the following lines to your CMakeLists.txt just before
the compiling the RzDLVTKView library below :


if(UNIX AND NOT WIN32)
  find_program(CMAKE_UNAME uname /bin /usr/bin /usr/local/bin )
  if(CMAKE_UNAME)
    exec_program(uname ARGS -m OUTPUT_VARIABLE CMAKE_SYSTEM_PROCESSOR)
    set(CMAKE_SYSTEM_PROCESSOR ${CMAKE_SYSTEM_PROCESSOR} CACHE INTERNAL
"processor type (i386 and x86_64)")
    if(CMAKE_SYSTEM_PROCESSOR MATCHES "x86_64")
      add_definitions(-fPIC)
    endif(CMAKE_SYSTEM_PROCESSOR MATCHES "x86_64")
  endif(CMAKE_UNAME)
endif(UNIX AND NOT WIN32)
