  I understand what you mean, what can be solved by an additional include file that includes the header file for the created categories  e.g.
  
    #include <projectname>_debug.h
  
  where the file content is something like
  
    #include "log1.h"
    #include "subdir2/log2.h"
  
  may be with an additional parameter
  
    COLLECT_HEADER        # uses ${PROJECT_NAME}_debug.h
  
  or
  
    COLLECT_HEADER    <filename>
  
  or by an additional function
  
    ecm_qt_logging_category_config(
         COLLECT_HEADER <filename>    # collect all defined category headers into this file
    )
  
  Also an additional function has the advantage to be able to define a common destination file for *.categories files
  
    ecm_qt_logging_category_config(
         CATEGORY_INSTALL               # store category entries for kdebugsettings in ${PROJECT_NAME}.categories
         CATEGORY_INSTALL <filename>    # store category entries for kdebugsettings in this filename
    )
  
  BTW: The parameter names are just proposals - there may be better names
