Oh, I didn't cover that branch because I saw it exist for WIN32 already, see https://github.com/Mbed-TLS/mbedtls/blob/fb12d9204dec811d0277a09bd93f9d745f44ce9f/library/CMakeLists.txt#L218-L220 which has been added in PR Mbed-TLS/mbedtls#8047. On the other hand, I saw it in the generated cmake config file MbedTLSTargets.cmake:

But I indeed didn't test it. If it's not work on find_package, maybe it's better to fix it on MbedTLS side?

The Android NDK-R23 github action failed, but on downloading OpenSSL. Not related to this PR. And I already can't re-run it.
As there were no objection to this fix, merging.
