title: How to print all the properties of a target in cmake?
body: <p>With the following cmake scrpt:</p>
  
  <pre><code>get_cmake_property(_variableNames VARIABLES)
  foreach (_variableName ${_variableNames})
      message(STATUS "${_variableName}=${${_variableName}}")
  endforeach()
  </code></pre>
  
  <p>We can print all the variables in the CMake project. Then my question is: is there a function that can print all the properties of a target? </p>
