Or do away with the static libraries in the first place...

I often do something like this:


lib/A/files.cmake:
------------------
set(LIB_A_SRCS)
foreach(s srcA1.c srcA2.c srcA3.c)
  list(APPEND LIB_A_SRCS "${CMAKE_SOURCE_DIR}/lib/A/${s}")
endforeach()

lib/B/files.cmake:
------------------
set(LIB_B_SRCS)
foreach(s srcB1.c srcB2.c srcB3.c)
  list(APPEND LIB_B_SRCS "${CMAKE_SOURCE_DIR}/lib/B/${s}")
endforeach()

lib/CMakeLists.txt:
--------------------
include(A/files.cmake)
include(B/files.cmake)
add_library(superduper ${LIB_A_SRCS} ${LIB_B_SRCS})
