 ### Example Build
 
-> The example build guide uses [Vcpkg](https://vcpkg.io/en/index.html) to fetch all dependencies. Note that Vcpkg is _not_ a requirement and is only used for convenience. One may provide dependencies through any other CMake mechanism. For details on how to install Vcpkg, refer to it's [Getting Started Guide](https://vcpkg.io/en/getting-started.html). The example build assumes targeting 64-bit Windows.

-_(Note: on Linux paths to dependent libraries are automatically handled by RPATH in both the build and install tree. On Windows all DLLs have to be on the `PATH`. Vcpkg copies dependent DLLs to the build tree, but in order to do the same in the install tree, sufficiently new CMake version is required.
