CMake's `FetchContent` module creates a `_deps` directory on the root (configurable by modifying `FETCHCONTENT_BASE_DIR`)

CMake may generate `compile_commands.json` file with `set(CMAKE_EXPORT_COMPILE_COMMANDS ON)` Option

CTestTestfile.cmake is automatically generated by CMake when invoking `enable_testing()` command in CMakeLists.txt.

Used by some build configurations, e.g. Xcode.
