You have to install cmake as the error tells you   you can follow this instructions https   www learnopencv com install-dlib-on-windows   or directly install cmake from here https   cmake org download   Once cmake is installed pip install dlib should work   I had vstudio building tools installed whe I did my test

Install dlib in Windows  download dlib from https   github com davisking dlib git  download camke from https   cmake org download   Extract cmake and configure it as Environment variable to the extracted path my it was C  Users admin Downloads cmake-3 8 1-win32-x86 cmake-3 8 1-win32-x86 bin  Now extract dlib zip file and go to dlib folder  Follow this commands  cd dlib test mkdir build cd build cmake    cmake --build   --config Release   Now go to Release folder which would be at dlib test build Release and execute this command     dtest exe --runall  This process takes time as cmake compiles all C   files so stay clam  Enjoy

None of the answers worked for me  This is what worked Assuming you have anaconda python 3 7 installed  1  Dowload and install cmake make sure to check the option to add cmake to system path during installation to avoid manually doing later   Download from this link cmake download  2  conda install -c conda-forge dlib

Just a quick update on what has worked for me  two years later   Davis King has provided two ways to add the latest python dlib  19 17 0  to any python environment in Windows 10 for me  Note  I run several Linux configs in Oracle VirtualBox but Windows 10 is my native OS which has access to the Nvidia GPU so i need an install on Windows 10   Cannot access the GPU - easily - through VirtualBox    First - the easiest   pip install dlib   and the website link  https   pypi org project dlib   And then it can be easily be build from sources  Download from https   pypi org simple dlib  and follow instructions on http   dlib net compile html   Also  just found another way to access with Visual Studio 2019  or 2017   Use vcpkg - see link https   vcpkg readthedocs io en latest    I built dlib 19 17 on Windows 10 with CMake and it worked fine but then I found vcpkg and now the dlib libraries are integral to the Visual Studio  I no longer need to add all the external links to C   and the linker The version in vcpkg is currently 19 16-1 and it is built with full CUDA support   Hope this helps others

Choose dlib  whl file according to your installed python version  For example if installed python version is 3 6 7   64bit system or if python is 3 5 0  32 bit then choose dlib-19 5 1-cp36-cp36m-win amd64 whl and dlib-18 17 100-cp35-none-win32 whl respectively   Bolded text says the python supporting version   Download wheel file from here or copy the link address  pip install dlib-19 5 1-cp36-cp36m-win amd64 whl   for above method  whl file shoud be in the working directory  or  Below link for python3 6 supporting dlib link  for python 3 5 u can replace with dlib 35 whl link  pip install https   files pythonhosted org packages 24 ea 81e4fc5b978277899b1c1a63ff358f1f645f9369e59d9b5d9cc1d57c007c dlib-19 5 1-cp36-cp36m-win amd64 whl sha256 7739535b76eb40cbcf49ba98d894894d06ee0b6e8f18a25fef2ab302fd5401c7

You need to install Cmake   dlib is an c   libary with python bindings  It needs to be builded first  My guess is this will happen automatically once you have installed Cmake
