Probably the Google-sponsored cryptography library you want to use depends on the language you're using... Not much point in using Tink if they don't expose a C-api or any other ergonomic form to make Rust bindings.

Project Oak (at Google) are working on Tink Rust: https://github.com/project-oak/tink-rust, although with this caveat:

This is not an official port of Tink, and is not supported by Google's cryptography teams.

Looks like an unusable mess for C++, this seems to be common problem with all of these crypto libraries-- just too many files and too complex of a build system(shocker not everyone uses CMake).

CMake is the de-facto standard for C++ build systems - its not the simplest, but it does an outstanding job at being widespread and reliable.

As someone who sometimes uses e.g. FreeBSD, I'll take CMake over someone's hand-crafted Makefile any day.
