CLion CMake Auto‑Reload and Profiling Interaction

CLion CMake Auto‑Reload Interaction with Profiling Runs for Bottleneck Measurement

Goal: obtain reliable bottleneck measurements before applying optimizations using CLion's integrated profiler while leveraging the CMake build system.

Constraints: the IDE’s auto‑reload feature may trigger full rebuilds when CMakeLists.txt changes, which can skew timing measurements; disabling auto‑reload avoids those rebuilds but raises uncertainty about when and how the symbol index is refreshed after a manual reload.

Does disabling auto-reload and manually reloading after a profiling run preserve up-to-date symbol indexes without causing a full rebuild? How can one ensure the profiler runs against the exact binary used for indexing when auto-reload is off? Are there recommended settings to balance measurement fidelity with IDE responsiveness?

CMake reload limits when multiple CMakeLists.txt files change in CLion 2023.2

CLion 2023.2 sometimes reloads only one CMakeLists.txt file when multiple are edited quickly, leaving other changes unprocessed. The behavior is documented but unresolved, especially for C++20 module projects. What is the status of this issue and can future releases address it?
