CMAKE_INSTALL_PREFIX not used

[scpeters]

In the root CMakeLists.txt, the CMAKE_INSTALL_PREFIX variable is replaced by the value of SimTK_INSTALL_PREFIX. In the comments (which were added in afc617e), it states that CMAKE_INSTALL_PREFIX is "always set to something incorrect by CMake". Is this just an issue with Windows? We use CMAKE_INSTALL_PREFIX regularly on Ubuntu and OSX for gazebo.

I think it was true a few years ago that CMAKE_INSTALL_PREFIX didn't properly deal with Windows installation, I think that has probably been fixed for a long time and SimTK_INSTALL_PREFIX is now unnecessary baggage. I remember that it was unable to deal with the byzantine rules for where to install 32 vs. 64 bit binaries on 32 or 64 bit Windows but I think they fixed that.

Aside from the root CMakeLists.txt, it looks like the SimTK_INSTALL_PREFIX variable is referenced from the following:

./SimTKmath/sharedTarget/CMakeLists.txt
./SimTKmath/staticTarget/CMakeLists.txt
./Platform/CMakeLists.txt
./Simbody/Visualizer/VisualizerGUI/CMakeLists.txt
./Simbody/sharedTarget/CMakeLists.txt
./Simbody/staticTarget/CMakeLists.txt
./debian/rules
./SimTKcommon/sharedTarget/CMakeLists.txt
./SimTKcommon/staticTarget/CMakeLists.txt
