.. and even if you pass in as a command line option
-D"CMAKE_INSTALL_PREFIX="  ?   I couldn't get FORCE to work either.
Possibly because I was using INTERNAL and not STRING.

It seems the following works (at least the cmake_install.cmake
commands appear to get generated appropriately).

FILE(TO_CMAKE_PATH "${CMAKE_INSTALL_PREFIX}" CMAKE_INSTALL_PREFIX)

Is there a CMPxxxx policy which deals with this which I have missed?

Thanks,
George.
