VRPN fixes (runtime, compilation, and external linkage)
- VRPN would not be found in
FindVRPN.cmake
on Linux ifiMSTK_USE_OMNI
was set to ON. - A name issue in
iMSTKConfig.cmake.in
would prevent external projects to link against iMSTK - An offset was applied on VRPN devices on the client side while there already was a way to set up offsets in the controller interface
