Effective Modern CMake

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

zmqimage.py -- classes to send, receive and display OpenCV images from a headless computer to a display computer using cv2.imshow()
# zmqimage.py -- classes to send, receive and display cv2 images via zmq
# based on serialization in pyzmq docs and pyzmq/examples/serialization
'''
PURPOSE:
These classes allow a headless (no display) computer running OpenCV code
to display OpenCV images on another computer with a display.
For example, a headless Raspberry Pi with no display can run OpenCV code
and can display OpenCV images on a Mac with a display.
USAGE:
# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.
