One way would be to have in your top level CMakeLists.txt file the  
list of all sources that go into the library. If your project is  
small enough you do not need to have a CMakeLists.txt file in each  
directory.

#-------- CMakeLists.txt ---------------

SET (Lib_sources
     ${CMAKE_CURRENT_SOURCE_DIR}/dir1/source.cpp
     ${CMAKE_CURRENT_SOURCE_DIR}/dir2/foo.cpp
)

ADD_LIBRARY(myLibrary ${Lib_sources})
