For now, I want to avoid copying all the data files to a new location. 
It's a lot easier for now to just place the binaries at the appropriate 
place in the source tree. I'm happy to see that INSTALL_TARGETS works 
on Windows now! I am encountering a strange issue with 
CMAKE_INSTALL_PREFIX now. In my top-level CMakeLists.txt, I have:

MARK_AS_ADVANCED(CLEAR CMAKE_INSTALL_PREFIX)
SET(CMAKE_INSTALL_PREFIX ${project_SOURCE_DIR})

When I start the CMake GUI (2.0-2), this variable appears as 
/usr/local. However, when I build the install project in Visual Studio, 
the targets are installed into the correct directory! The 
CMakeCache.txt still contains /usr/local, and if I uncomment the lines 
above, the targets are installed into C:/usr/local. Something doesn't 
seem to match between the GUI and the interpreted value during the 
install. Is there some way that I can set the CMAKE_INSTALL_PREFIX in 
CMakeLists.txt and have the GUI reflect the updated value?
