libssh2 + CURL_DISABLE_DIGEST_AUTH + CURL_DISABLE_AWS build error

[vszakats]

I did this

Building with:

cmake [...] \
  -DCURL_DISABLE_DIGEST_AUTH=ON -DCURL_DISABLE_AWS=ON \
  -DCURL_USE_SCHANNEL=ON \
  -DCURL_USE_LIBSSH2=ON \
  -DLIBSSH2_INCLUDE_DIR=.../libssh2/_x64-win-ucrt/usr/include \
  -DLIBSSH2_LIBRARY=.../libssh2/_x64-win-ucrt/usr/lib/libssh2.a

Results in:

The same happens without Schannel by setting -DCURL_DISABLE_NTLM=ON instead.

Enabling e.g. quictls, doesn't fix it.

Possibly regression from e92edfb #11490

I expected the following

No error

curl/libcurl version

8.5.0-DEV 46878b9

operating system
