# Most of the setup is copy&paste, how to reproduce (the hard way..):
# 0. try to use `cgreen` as normal `cmake` subproject
# 1. add bare git-wrap for cgreen -> `subprojects/cgreen.wrap`:
#    > [wrap-git]
#    > url = https://github.com/cgreen-devs/cgreen.git
#    > revision = master
#    > depth = 1
# 2. in `<project_root>/meson.build`, add normal cmake subproject setup:
#    > cmake = import('cmake')
#    > cgreen = cmake.subproject('cgreen')
#    > # you may want to lookup available targets before
#    > message('CMaket targets:\n - ' + '\n - '.join(cgreen.target_list()))
#    > cgreen_dep = cgreen.dependency('cgreen_shared')
#    > cgreen_runner_dep = cgreen.dependency('cgreen_runner')
# 3. compile with meson (`meson compile -C <builddir>`)
# 4. look up generated meson.build in `<builddir>/subprojects/cgreen/meson.build`
# 5. copy & paste into subprojects/packagefiles
#    a. add meson overrides for wanted dependencies:
#       > meson.override_dependency('cgreen', cgreen_shared_dep)
#       > meson.override_find_program('cgreen-runner', cgreen_runner)
#    b. remove all other generated targets
# 6. fix the errors you faced before :)
#    a. remove redundant `FILENAME` defines
#    b. checkout how `config.h` is generated (see `subprojects/cgreen/config.h.cmake`)
#    c. apply that to [meson setup](https://mesonbuild.com/Configuration.html)
#       or create a minimal working substitute ;) -> see below (:30-35)
