Makes 'nmake install' work.

In BUILDING.WIN32, the following line exists:

  nmake install

This doesn't work because the install targets never get built because of
the code:

  IF(NOT WIN32)
    INSTALL(...)
    ...
  ENDIF()

in several CMakeLists.txt files. There's no reason to disallow INSTALL
on Windows, even if most developers (who use devenv on its own) will
never use it.
