If you are new with Conan, we recommend to read the section how to consume packages.

If you need additional assistance, please ask a question in the Conan Center Index repository.

Simplest use case consuming this recipe and assuming CMake as your local build tool:

[requires]
openjpeg/2.5.0
[generators]
CMakeDeps
CMakeToolchain
[layout]
cmake_layout
from conan import ConanFile
from conan.tools.cmake import cmake_layout


class ExampleRecipe(ConanFile):
    settings = "os", "compiler", "build_type", "arch"
    generators = "CMakeDeps", "CMakeToolchain"

    def requirements(self):
        self.requires("openjpeg/2.5.0")

    def layout(self):
        cmake_layout(self)

Now, you can run this Conan command to locally install (and build if necessary) this recipe and its dependencies (if any):

$ conan install conanfile.txt --build=missing
