As a VS2005 Express user I do not want to have to manually copy 3 support files partway into a build of the viewer source code.
There used to be a command line -D option into develop.py that allowed me, as a VS 2005 Express user, to specify where to find:
At some point after v2.1 Copy3rdPartyLibs.cmake, which used -DMSVC_REDIST_PATH, was rewritten and this option removed.
Currently, as a VS2005 Express user, there is no automatic way of detecting these 3 files and copying them to the right place. I have to manually drop them into a build folder once the compiler has been running for a few seconds (the place they get dropped into does not exist until the compiler has been going for a short time) and at some point re-run the compiler so it detects them properly.
