 1. Generate project:
 
-        cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_TOOLCHAIN_FILE="…/vcpkg/scripts/buildsystems/vcpkg.cmake" -DVCPKG_TARGET_TRIPLET=x86-windows-static -DRust_CARGO_TARGET="i686-pc-windows-msvc" ..

     If necessary, the rust tool-chain version can be specified via `-DRust_TOOLCHAIN="1.75-i686-pc-windows-msvc"`.

 #### Notes
 
 purple-presage must be built with MSVC. MinGW's GCC encountered a number of issues such as [incompatibility with rustc versions newer than 1.69](https://github.com/rust-lang/rust/issues/112368) and not shipping libbcrypt by default.
