[CMake] ninja generator and add_custom_target bug

[Petr Kmoch]

Hi Russell,

you might want to add VERBATIM to the custom target, so that command-line
arguments are escaped properly:

ADD_CUSTOM_TARGET(uninstall
  COMMAND echo "\nRemoving installed files:"
  COMMAND cat ${CMAKE_CURRENT_BINARY_DIR}/install_manifest.txt | xargs rm
-fv
  VERBATIM
)

See the docs:
http://www.cmake.org/cmake/help/v3.0/command/add_custom_target.html

I don't know whether it helps, but it might.

Petr
