cmake - Add target to all subfolders -

i'm working on library project built follows

base/ cmakelists.txt src/ tools/ cmakelists.txt tests/ cmakelists.txt debug/ release/

the main cmakelists.txt, in base/ contains target build library source in src/ , have configure create debug/ , release/ , phone call cmake -dcmake_release_type=<debug|release> .. build structures.

this results in next structure

debug/ makefile tests/ makefile tools/ makefile

the programs built in tools/ , tests/ create output files , i'm trying create clean_output target every makefile in created build structure.

i've used add_custom_target(clean_output rm -rf *.ext) doesn't carry makefile files in tests/ , tools/. i've tried add together same command in cmakelists.txt files in directories, error message can't define target defined within same project.

i have tried utilize working_drectory in combination cmake_current_list_dir , cmake_current_binary_dir no avail.

does know how define custom target in directories of project?

edit: not trying add together files standard clean target. i'm trying create additional clean_output target remove files while keeping executables in place.

you can specify working directory , several commands execute in 1 target. btw can utilize cmake -e remove_directory:

add_custom_target( clean_output command "${cmake_command}" -e remove_directory "${cmake_current_list_dir}/directory/with/exts" command "${cmake_command}" -e remove_directory "${cmake_current_list_dir}/other-dir/with/exts" working_directory "${cmake_current_list_dir}" )
