cmake - Prevent make install from propagating to external projects -


let's have 3 projects. a, b, , c, executable , b , c static libraries required a. depends on b. , b depends on c.

i have 3 cmakelists.txt, 1 each project.

in a, build b using externalproject_add , add_dependencies. relies on b using install step put headers , library file in known places can find headers compilation , link.

b uses externalproject_add , add_dependencies build c. again, install step important here because allows both b , find header files.

i can build no problem. do, want able install executable. consists of bundling data via copy copying executable known place. executable requires data in particular location relative it.

so install of executable looks this:

install(targets ${project_name} runtime destination bin library destination lib archive destination lib) install(directory ${cmake_source_dir}/resources/         destination ${project_name})

when run make install notice go down chain, checks if targets built , installs them. make sense happens. however, isn't ideally want (the copying can take while, i'd prefer "re-install" of b , c not happen.

is there viable approach take can either make make install not go through chain, or there invocation can use this?

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
