Libs And Frameworks

Modern target-based CMake for C++ — projects, libraries, dependencies (`find_package`, `FetchContent`), install/export, idioms and anti-patterns

OpenMP for C++ — fork/join, parallel loops and schedules, data sharing, reductions and `atomic`, sections and tasks, SIMD, synchronization

Protobuf in C++ — `.proto` schema, generated message API, binary/text/JSON serialization, `oneof`/repeated/map, arenas, schema evolution, sharing schemas with Python

Boost in modern C++ — what's been standardized, `variant`/visitor, `geometry` (distance/predicates/boolean ops/R-tree), Asio, Program Options, Multi-Index

Eigen linear algebra — matrices, storage order, decompositions and solvers, geometry (rotations/quaternions/axis-angle for SLAM, `wxyz` vs `xyzw`, homogeneous coords), aliasing and the `auto`-with-expression-templates pitfall

Bazel for C++ and Python — Bzlmod and legacy WORKSPACE, BUILD files, `cc_*` and `py_*` rules, visibility, external deps, configurations, remote caching, Starlark macros and rules
