Answer 1

install visual studio with Visual C++ tools for CMake and then try to run it again.

Answer 2

If you are not developing in C++, you would need a redistributable for the language installed on your PC.
You do not have to install the whole Visual Studio for this. Just download a build tool for the 64bit arch from the following link and install it. Microsoft Visual Studio 2019 Build Tool
Try running the dlib installation after that and it should work
