# Configures CMake to generate a 'compile_commands.json' file in the build directory.
# This file is used by many IDEs and language servers (e.g., VS Code, CLion)
# to provide intelligent code features like autocompletion, go-to-definition, and static analysis.

# Includes the CMakeLists.txt files from the specified subdirectories.
# This makes the targets (libraries) defined in those subdirectories available in the current scope.
# The order is important: libraries must be defined before they are linked.

# Links the executable target 'cmake_tutorialApp' to the specified libraries.
# - PRIVATE: Indicates that 'cmake_tutorialApp' needs these libraries for its own compilation/linking,
# but targets that link to 'cmake_tutorialApp' do NOT need them.
# CMake automatically propagates the PUBLIC/INTERFACE include directories from lib1, lib2, and lib3
# to cmake_tutorialApp, so explicit target_include_directories is not needed here.
