[CMake] Correct syntax for CPACK_NSIS_CREATE_ICONS [SOLVED]

[Bill Hoffman]

Another way to do this without the insane \\\\\\\\\\\\\ stuff, is to use 
  a configured file like CMake does:

   CONFIGURE_FILE("${CMake_SOURCE_DIR}/CMakeCPackOptions.cmake.in"
     "${CMake_BINARY_DIR}/CMakeCPackOptions.cmake" @ONLY)
   SET(CPACK_PROJECT_CONFIG_FILE 
"${CMake_BINARY_DIR}/CMakeCPackOptions.cmake")



The file referenced by CPACK_PROJECT_CONFIG_FILE will be loaded by cpack 
at package time.
