Error when installing dlib on Python 3.5 using Windows 10

Question

EDIT: Looks like I have to install Visual Studio 2015...Can I install dlib without VS 2015? I already have older versions pre-installed with Windows.

I am using Python 3.5, trying to install dlib on PyCharm in the terminal and this is what I am getting, and every search on these errors I do... I find stuff on Visual Studio which I don't have the GUI + I don't have vcvarsall.bat in the VC folder of any of the Visual Studio versions (8, 11, 12, 14). I have searched a good amount before posting this question on the Web. Do I need to download Visual Studio latest version to get vcvarsall.bat ?

This is CMakeLists.txt:

cmake_minimum_required(VERSION ${CMAKE_VERSION})
project(IntelFortranImplicit Fortran)
add_custom_command(
  OUTPUT output.cmake
  COMMAND ${CMAKE_COMMAND} -P ${IntelFortranImplicit_SOURCE_DIR}/detect.cmake
  )
add_library(FortranLib hello.f output.cmake)

This is the error when I do: pip install dlib
