Sorry, I don't have clang's compiler environment. I use gcc not clang.
I tried it locally but didn't reproduce this issue:

libsodium provides CMake targets:

  find_package(unofficial-sodium CONFIG REQUIRED)
  target_link_libraries(main PRIVATE unofficial-sodium::sodium)

libsodium provides pkg-config modules:

Sorry, I don't have clang's compiler environment. I use gcc not clang.

If you have a suitable NDK, you have clang.
gcc in NDK has been deprecated a while ago. It is not the default with NDK r25 which is used in VCPKG CI.

$ gcc --version
gcc (Ubuntu 9.4.0-1ubuntu1~20.04.2) 9.4.0

This is the not compiler used when building for android. See config or install log.

FTR the error is reproducible with NDK r26.
