 + The project structure changed:
   + Public API headers moved from `include/` to the `include/bit7z/` folder, so `#include` directives now need to prepend `bit7z/` to the included header name (e.g., `#include <bit7z/bitfileextractor.hpp>`).

-For manually building the library:
-
-```bash
-cd <bit7z folder>
-mkdir build && cd build
-cmake ../ -DCMAKE_BUILD_TYPE=Release
-cmake --build . -j --config Release
-```
-
-A `.lib`/`.a` library file will be produced in the `<bit7z folder>/lib/<arch>/` folder.

-A more detailed guide on how to build this library is available [here](https://github.com/rikyoz/bit7z/wiki/Building-the-library).
-
-Once built, you can copy the library file and bit7z's `include` folder in the desired subfolders of your project, and then manually link the library and its runtime dependencies to your application, e.g., in your CMake project:
-
-```cmake
-target_include_directories(${YOUR_TARGET} PRIVATE "<path-to-bit7z-include-folder>")
-find_library(BIT7Z_LIB bit7z HINTS "<path-to-bit7z-lib-folder>")
