Changing any build settings from within the IDE will not work because 
the next time CMake runs (possibly automatically during the build) it 
will just overwrite the project files with the original settings.

Currently I don't think support is implemented in CMake for 64-bit 
builds with Visual Studio.  Please submit a feature request here:

Meanwhile you _might_ be able to get things working by using the "NMake 
Makefiles" generator (starting with an new empty build tree) and setting 
the CMAKE_C_FLAGS* and CMAKE_CXX_FLAGS* variables in the cache (turn on 
advanced view)  to contain the proper flags for 64-bit builds.
