To reduce the diff between tests CMakeFiles.txt, and syncing with
autotools, which already used the `BUNDLE` variable like this.
Also:
- fold lines that went over 132 chars after this change.
- autotools: sync order of macros with cmake.
Closes#17667
- GHA/windows: make a mingw autotools build static only.
- GHA/windows: fix a CI script issue with the build above.
- src: fix to pass `LIBCURL_PC_LIBS_PRIVATE` instead of `LINKFLAGS`.
This makes the libs propagate to tunits, making the local hack there
unnecessary. `LINKFLAGS` had this single use in the repo, and it was
empty in local tests.
- tests: drop passing redundant `LIBCURL_PC_LDFLAGS_PRIVATE`.
- tests: drop redundant target name from config variables.
- examples, tests/client: drop `LIBDIR` temp variables with single uses.
- examples, tests: formatting to sync `Makefile.am` scripts with each
other.
Closes#17661
Replacing `fprintf()`. `curl_mfprintf()` is a public libcurl API.
Following the same change made for libtests.
Follow-up to 255aac56f9#17253Closes#17651
To have all the tests binaries directly under the tests directory.
There seems to be no issue adding non-http test clients to this subdir.
