 ### Compilation
 
 This project is built with cmake and vcpkg and requires wxwidgets library.
-Install vcpkg first, then install wxwidgets into vcpkg and run cmake. Make sure to define `CMAKE_TOOLCHAIN_FILE` pointing to `vcpkg/scripts/buildsystems/vcpkg.cmake`. Optionally pass `VCPKG_TARGET_TRIPLET="x64-windows-static"` and `CMAKE_UPX_PATH=path/to/upx.exe` to link statically and compress the executable.
