Simple simdutf demo for vcpkg

This project builds a simple executable that depends on simdutf, under Windows and Linux.

After installing vcpkg and installing simdutf through it (e.g., vcpkg install simdutf:x64-windows or vcpkg install simdutf), you can build with CMake using a couple of command lines.

You need to pass the location of your vcpkg/scripts/buildsystems/vcpkg.cmake file to CMake:

cmake -DCMAKE_TOOLCHAIN_FILE=<location> -B build
cmake --build build
