Use PUBLIC, PRIVATE, and INTERFACE in target_link_libraries to control which dependencies reach consumers and avoid unnecessary rebuilds.
Thin LTO gives most whole-program optimization benefits with manageable link-time cost. Enable -flto=thin -O2 on both compile and link lines, install the linker plugin, audit for latent UB, and expect 3-7% speedup on cross-file hot paths.
CMake's target-based API with PUBLIC/PRIVATE/INTERFACE visibility stops private headers from leaking into downstream consumers. A three-target worked example shows how compile_commands.json reflects correct propagation, and generator expressions enable relocatable installs.
Compiler reports header not found even though the file exists. A diagnostic guide for CMake include path failures with cause table, ordered checks, fixes tied to findings, and escalation criteria.
Bazel remote caching skips redundant rebuilds by sharing action outputs across machines, but only hermetic builds stay correct. Learn the mechanics, a minimal setup, and the operational trade-offs.
Modern CMake’s target‑based API replaces global settings with per‑target visibility, using PUBLIC/PRIVATE/INTERFACE and generator expressions for conditional compile flags. A three‑target example shows how the rules propagate and keep Debug/Release builds separate.
CLion treats CMakeLists.txt as the single source of truth, eliminating parallel project models but introducing reload latency and macro parsing gaps. CMake Presets solve cross-platform config sharing—if you script the reload instead of relying on auto-sync.
Use PUBLIC, PRIVATE, and INTERFACE on targets instead of global commands so CMake propagates include paths and link dependencies transitively and correctly.
CMake's find_package is a cached search that yields imported targets. A worked Threads example shows how REQUIRED, version checks, cache resets, and verbose link inspection prevent the usual integration failures.
