In your Dockerfile.

FROM python:3
WORKDIR ./app
COPY ./requirements.txt .
RUN pip install -U pip wheel cmake
RUN pip install -r requirements.txt
COPY . ./app
ENTRYPOINT [ "python", "./app.py" ]

first install cmake and wheel with pip, the packages you install from the requirement.txt file are first downloaded and then installed, for this reason it fails to install dlib.

In your requirements.txt put CMake as first
