This is your error:

CMake must be installed to build the following extensions: dlib

Which tells it all. For the compilation to work, you need to install cmake.

But, since you are using anaconda, there is no reason to use pip to install dlib. It is actually not even recommended to use pip to install packages to your conda environment if it can be avoided. That said, simply use:

conda install -c conda-forge dlib

to install

I cant install dlib using pip. what is the problem?
