Conan package recipe for opencv
OpenCV (Open Source Computer Vision Library) is an open source computer vision and machine learning software library.
The packages generated with this conanfile can be found on Bintray.
Issues
If you wish to report an issue or make a request for a package, please do so here:
For Users
Basic setup
$ conan install opencv/4.3.0@conan/stable
Project setup
If you handle multiple dependencies in your project is better to add a conanfile.txt
[requires]
opencv/4.3.0@conan/stable
[generators]
cmake
Complete the installation of requirements for your project running:
$ mkdir build && cd build && conan install ..
Note: It is recommended that you run conan install from a build directory and not the root of the project directory. This is because conan generates conanbuildinfo files specific to a single build configuration which by default comes from an autodetected default profile located in ~/.conan/profiles/default . If you pass different build configuration options to conan install, it will generate different conanbuildinfo files. Thus, they should not be added to the root of the project, nor committed to git.
Build and package
The following command both runs all the steps of the conan file, and publishes the package to the local system cache. This includes downloading dependencies from "build_requires" and "requires" , and then running the build() method.
$ conan create . conan/stable
