[CMake] dependlocal problem

[Alexander Neundorf]

Hi, 
 
I'm trying to build kdevelop with cmake and wrote some new macros. Now I 
see the following: when starting make in the kdevelop root directory, it 
traverses and builds as expected, but it seems for dependlocal it starts 
make for every file. Is this expected behaviour ? 
The result you see below, this takes quite long (more than 1 minute just 
the dependlocal) on a fast machine (2GHz).

This seems to be the macro which causes this effect: 
 
#check every file for "include <blah.moc> and if so, creates the rules 
#for the moc file 
MACRO(KDE_AUTOMOC) 
  SET(_matching_FILES ) 
  FOREACH (_current_FILE ${ARGN}) 
    IF (EXISTS ${CMAKE_CURRENT_SOURCE_DIR}/${_current_FILE}) 
      GET_FILENAME_COMPONENT(_basename ${_current_FILE} NAME_WE) 
      SET(_moc ${_basename}.moc) 
       
      FILE(READ ${CMAKE_CURRENT_SOURCE_DIR}/${_current_FILE} _contents) 
       
      STRING(REGEX MATCH "#include.+${_moc}" _match "${_contents}") 
 
      IF(_match) 
        SET(_moc_FILE ${CMAKE_CURRENT_BINARY_DIR}/${_basename}.moc) 
        SET(_header ${CMAKE_CURRENT_SOURCE_DIR}/${_basename}.h) 
 
        ADD_CUSTOM_COMMAND(OUTPUT ${_moc_FILE} 
          COMMAND moc 
          ARGS ${_header} -o ${_moc_FILE} 
          DEPENDS ${_header} 
          )                 
 
        ADD_FILE_DEPENDANCY(${CMAKE_CURRENT_SOURCE_DIR}/${_current_FILE} 
${_moc_FILE}) 
 
      ENDIF(_match) 
    ENDIF (EXISTS ${CMAKE_CURRENT_SOURCE_DIR}/${_current_FILE}) 
  ENDFOREACH (_current_FILE) 
ENDMACRO(KDE_AUTOMOC) 
 
MACRO(ADD_FILE_DEPENDANCY file) 
   SET(${file}_deps ${${file}_deps} ${ARGN}) 
   SET_SOURCE_FILES_PROPERTIES( 
      ${file} 
      PROPERTIES 
      OBJECT_DEPENDS 
      "${${file}_deps}" 
   ) 
ENDMACRO(ADD_FILE_DEPENDANCY) 
 
I use it this way: 
 
SET(kdevpropertyeditor_SRCS 
childproperty.cpp 
pcombobox.cpp    
pdummywidget.cpp   
ppointedit.cpp      
propertymachinefactory.cpp   
pstringlistedit.cpp 
multiproperty.cpp   
pcursoredit.cpp       
pfontbutton.cpp    
prectedit.cpp        
propertywidget.cpp           
psymbolcombo.cpp 
...more files 
) 
 
KDE_AUTOMOC(${kdevpropertyeditor_SRCS}) 
 
INCLUDE_DIRECTORIES(${CMAKE_CURRENT_SOURCE_DIR}) 
 
ADD_LIBRARY(kdevpropertyeditor SHARED ${kdevpropertyeditor_SRCS}) 
 
The ADD_CUSTOM_COMMAND() seems to be the command which cause this strange 
behaviour. Any ideas what's going on there or how I can find out ? 
 
I'm using cmake cvs from some weeks ago. 
 
Bye 
Alex
