```
--enable-lto
--with-distro=LibreOfficeAndroidAarch64
--with-android-sdk=$HOME/bin/android_sdk
--with-android-ndk=$HOME/bin/android_sdk/ndk/27.2.12479018

autogen.sh failed with the following message:
```
checking which libcmis to use... internal
checking whether clang++ supports C++20... configure: error: no
