I propose to print message if one of the following holds:
* CMAKE_DEBUG_MESSAGES is true;
* CMAKE_DEBUG_MESSAGES_FileName is true, where FileName is 
CMAKE_CURRENT_LIST_FILE's name without extension;
* Current list file is CMakeLists.txt and 
CMAKE_DEBUG_MESSAGES_CurrentDirectory is true.

This will allow

# Turn all debug messages
-DCMAKE_DEBUG_MESSAGES=ON
# Turn all debug messages in FindBoost.cmake
-DCMAKE_DEBUG_MESSAGES_FindBoost=ON
# Turn all debug messages in mysubdir/CMakeLists.txt 
-DCMAKE_DEBUG_MESSAGES_mysubdir=ON
# Turn all debug messages in **/CMakeLists.txt
-DCMAKE_DEBUG_MESSAGES_CMakeLists=ON
