Not sure. 
I attached a simple testcase. 
If you look in cmake-acc/foo/CMakeLists.txt, you will see an 
ADD_CUSTOM_COMMAND() which depends on config.h . It doesn't find 
cmake-acc/foo/config.h, but instead uses cmake-acc/config.h (which is not 
what I would expect). Just remove the ${CMAKE_CURRENT_XXX_DIR}s in 
cmake-acc/foo/CMakeLists.txt too see what I mean. (cmake cvs june 29th, 
unix makefile generator). 
 
Bye
