CMake C++ example project for depthai-core library

CMake example project which serves as a template on how to quickly get started with C++ and the depthai-core library.

Depthai library dependencies

• cmake >= 3.20
• C/C++17 compiler

Prerequisites

OpenCV - optional (for this example only)

OpenCV is required to run the out-of-box example. You can install OpenCV using one of the options below:

• Ubuntu 20.04, Ubuntu 22.04, Ubuntu 24.04 - sudo apt install libopencv-dev
• Fedora36+ - sudo dnf install opencv-devel
• MacOS - brew install opencv
• Or install from package / sources (Windows and other OSes) https://docs.opencv.org/master/d0/d3d/tutorial_general_install.html

Building

Clone and build depthai-core

git clone https://github.com/luxonis/depthai-core.git --recursive && cd depthai-core
cmake -Bbuild -S. -DBUILD_SHARED_LIBS=ON -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/path/to/install/dir
cmake --build build --target install --parallel 4

Navigate to your example project's root folder.

Build example project

cmake -Bbuild -S. -DCMAKE_PREFIX_PATH=/path/to/install/dir
cmake --build build --parallel 4

Make sure to change the /path/to/install/dir to a desired location on your filesystem. On Linux-based systems, if the -DCMAKE_INSTALL_PREFIX=/path/to/install/dir option is omited, depthai-core will get installed to /usr/local. In that case, you don't need to specify the -DCMAKE_PREFIX_PATH=/path/to/install/dir option.

Running

To run the example application 'myapp', navigate to build directory and run 'myapp' executable

./myapp
