[CMake] CMake, Cpack and NSIS woes.

[Andrew Maclean]

The only way that I can get this to work is to do this:

  string(REPLACE "/" "\\\\" NATIVE_CMAKE_INSTALL_PATH ${INSTALL_DIRECTORY})
  set(CPACK_PACKAGE_INSTALL_DIRECTORY ${NATIVE_CMAKE_INSTALL_PATH}
CACHE INTERNAL "")

where the INSTALL_DIRECTORY is: VTK_Utilities/CMakeTest_1.1

This lets me create both the Package and also lets me
install/uninstall. If I don't convert the path to native the NSIS will
not interperet / as \. Using the native conversion gives a warning
that \C is an invalid escape sequence but it will install. If I change
it to:
   string(REPLACE "/" "\\\\\\\\" NATIVE_CMAKE_INSTALL_PATH ${INSTALL_DIRECTORY})

Then the \\ is treated as \  when windows builds the path upon
installation. I think this is a little risky.

If CPACK_SET_DESTDIR is on then the install/uninstall installs to a
subdirectory under the temporary directory. This seems to have no
effect on packaging with NSIS.
