Summary0015461: Ninja generator does not honor COMMENT for TARGET POST_BUILD commands
DescriptionUpon adding a TARGET POST_BUILD command to make an alias link for a built library, the Ninja system does not print my defined COMMENT.
Steps To ReproduceDefine a custom command as a POST_BUILD command to (e.g.) a library target, and define a COMMENT.

Run CMake -GNinja.

Run ninja > log.txt 2>&1

Fail to see your COMMENT in log.txt.
Additional InformationThe COMMENT is printed as expected with the UNIX Makefile generator in CMake 3.2.1.

The actual command we used:

function(cet_lib_alias LIB_TARGET)
  foreach(alias ${ARGN})
    add_custom_command(TARGET ${LIB_TARGET}
      POST_BUILD
      COMMAND ln -sf $<TARGET_LINKER_FILE_NAME:${LIB_TARGET}>
      ${CMAKE_SHARED_LIBRARY_PREFIX}${alias}${CMAKE_SHARED_LIBRARY_SUFFIX}
      COMMENT "Generate / refresh courtesy link ${CMAKE_SHARED_LIBRARY_PREFIX}${alias}${CMAKE_SHARED_LIBRARY_SUFFIX} -> $<TARGET_LINKER_FILE_NAME:${LIB_TARGET}>"
      VERBATIM
      WORKING_DIRECTORY ${LIBRARY_OUTPUT_PATH})
  endforeach()
endfunction()
