mhm,

i swapped URL for the SOURCE_DIR, yes, and there is also no
DOWNLOAD_COMMAND or UPDATE_COMMAND. My build always reports 'succeeded'
without doing anything.

well, i just have:


------->
ExternalProject_Add(${proj}
  SOURCE_DIR ${Log4Qt_SOURCE_DIR}
  BINARY_DIR ${proj}_bin
  INSTALL_DIR ${proj}_install
  INSTALL_COMMAND ""
  CMAKE_GENERATOR ${gen}
  CMAKE_ARGS
    ${common_args}							
-DQT_QMAKE_EXECUTABLE:FILEPATH=${QT_QMAKE_EXECUTABLE}
  CMAKE_CACHE_ARGS
    -DCMAKE_INCLUDE_CURRENT_DIR:BOOL=ON
   DEPENDS ${proj_DEPENDENCIES}
		 )
<-------

with common_args beeing:

  -DBUILD_TESTING:BOOL=${ep_build_testing}
  -DCMAKE_INSTALL_PREFIX:PATH=${ep_install_dir}
  -DBUILD_SHARED_LIBS:BOOL=ON
