How can I get Meson to run a target for all my configured targets?

[smcallis]

Basically I want to write my own clang-tidy target because I simply cannot get the built-in one to stop emitting tidy information for system headers and sub-projects. clangd-tidy is faster anyways, so I'd like to use that, but I'd like to avoid having to manually add my source files to a variable to do it. Can meson call an external script with all its source files?

Write a script around the output of meson introspect --targets or compile_commands.json.

Here is an example of the latter: https://gitlab.com/qemu-project/qemu/-/blob/master/scripts/check_sparse.py
