curl builds tests with CMake when explicitly building the `testdeps` target. It's not built by default. It seems overkill to have a curl-specific variant of this (over CMake's `BUILD_TESTING`) to disable generating this target. Its history also doesn't make it obvious why this was necessary, and there was a long debate how to do it, by the time the original submitter abandoned CMake. The option also remained uninitialized and thus undocumented. Let me know if I missed something. Ref: curl#6036 Ref: 3a1e798 curl#6072 Closes curl#16134

I wonder if this option is useful. According to the linked Issues, its goal is to disable building tests for curl specifically, when in nested projects
BUILD_TESTINGwould disable this for all other projects as well.But, tests are not built in curl by default regardless of these settings. These control if the
testdepstarget is present or excluded at the "generation" step. Excluding this target saves near zero time there.Test targets are build only when explicitly building the
testdepstarget. Maybe this target is also used in other projects? GitHub search reports this string being present in just a tiny number of projects: https://github.com/search?q=testdeps+language%3Acmake&type=codeIf it would be a widely used name, perhaps renaming to
curl-testswould be a better way to go. (and match how we fixed this for other target names.)Or perhaps there is another shared mechanism to kick off (actually) building tests?
Any thoughts?
