For Users

Basic setup

$ conan install opencv/4.1.1@conan/stable

Project setup

If you handle multiple dependencies in your project is better to add a conanfile.txt

[requires]
opencv/4.1.1@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

Qt5 builds

Below is an example of how to configure Qt5 enabled OpenCV dependencies in your own project:

cmake_minimum_required(VERSION 3.15)
project(my-opencv-qt-project)

include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake)
conan_basic_setup(TARGETS)

set(Qt5_DIR ${CONAN_QT_ROOT})
find_package(Qt5 CONFIG COMPONENTS Core Gui Widgets Test Concurrent REQUIRED)

target_link_libraries(CONAN_PKG::opencv INTERFACE Qt5::Core Qt5::Gui Qt5::Widgets Qt5::Test Qt5::Concurrent)
target_link_libraries(${PROJECT_NAME} CONAN_PKG::opencv)

Add Remote

Conan Community has its own Bintray repository, however, we are working to distribute all package in the Conan Center:

$ conan remote add conan-center "https://conan.bintray.com"
