# Even though we are using CMake's ctest for testing, we still define our own `make test` target
# rather than use its default for many reasons:
# * CMake doesn't run tests in-proc or even add each tests as an individual node in the ninja
# dependency tree, instead it just bundles all tests into a target called `test` that always just
# shells out to `ctest`, so there are no build-related benefits to not doing that ourselves.
# * CMake devs insist that it is appropriate for `make test` to never depend on `make all`, i.e.
# running `make test` does not require any of the binaries to be built before testing.
# * The only way to have a test depend on a binary is to add a fake test with a name like
# "build_fish" that executes CMake recursively to build the `fish` target.
# * It is not possible to set top-level CTest options/settings such as CTEST_PARALLEL_LEVEL from
# within the CMake configuration file.
# * Circling back to the point about individual tests not being actual Makefile targets, CMake does
# not offer any way to execute a named test via the `make`/`ninja`/whatever interface; the only
# way to manually invoke test `foo` is to to manually run `ctest` and specify a regex matching
# `foo` as an argument, e.g. `ctest -R ^foo$`... which is really crazy.
# The top-level test target is "fish_run_tests".
