Can using CMake help manage the libpng dependency and avoid the 'png.h' error?

Yes, CMake is an excellent tool for managing dependencies like libpng. You can use `find_package(PNG REQUIRED)` in your `CMakeLists.txt` file to locate libpng. CMake will then automatically set the necessary include directories and link libraries, simplifying the build process and reducing the chance of encountering the 'png.h' not found error. You can then use `target_link_libraries(your_target PNG::PNG)` to link against the library.
