Improved @AlwaysTraining's and @PaulMolodowitch's answers.
Solves problem with INTERFACE_LIBRARY described in kyb's comment

Functionally my implementation does at most the same as @PaulMolodowitch's implementation. But it is more laconic.

## Get all properties that cmake supports
execute_process(COMMAND cmake --help-property-list OUTPUT_VARIABLE CMAKE_PROPERTY_LIST)
## Convert command output into a CMake list
STRING(REGEX REPLACE ";" "\\\\;" CMAKE_PROPERTY_LIST "${CMAKE_PROPERTY_LIST}")
STRING(REGEX REPLACE "\n" ";" CMAKE_PROPERTY_LIST "${CMAKE_PROPERTY_LIST}")

list(REMOVE_DUPLICATES CMAKE_PROPERTY_LIST)

function(print_target_properties tgt)
    if(NOT TARGET ${tgt})
      message("There is no target named '${tgt}'")
      return()
    endif()

    foreach (prop ${CMAKE_PROPERTY_LIST})
        string(REPLACE "" "${CMAKE_BUILD_TYPE}" prop ${prop})
        get_target_property(propval ${tgt} ${prop})
        if (propval)
            get_target_property(propval ${tgt} ${prop})
            message ("${tgt} ${prop} = ${propval}")
        endif()
    endforeach(prop)
endfunction(print_target_properties)
