Add a test collection target in each directory and then add
dependencies among them:

$ grep all_test */CMakeLists.txt
A/CMakeLists.txt:  add_custom_target(A_tests)
A/CMakeLists.txt:  add_dependencies(A_tests Atest1 Atest2)
B/CMakeLists.txt:  add_custom_target(B_tests)
B/CMakeLists.txt:  add_dependencies(B_tests Btest1 Btest2)
C/CMakeLists.txt:  add_custom_target(C_tests)
C/CMakeLists.txt:  add_dependencies(C_tests Ctest1 Ctest2)
C/CMakeLists.txt:  add_dependencies(C_tests A_tests B_tests)
