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]
optional-lite/3.6.0
[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("optional-lite/3.6.0")

    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

Useful information to take into account to consume this library:


These are the main declared targets:

  • CMake package name(s): optional-lite
  • CMake target name(s): nonstd::optional-lite
  • optionallite => nonstd::optional-lite
    
  • pkg-config file name(s): optional-lite.pc
  • optionallite => optional-lite-optionallite.pc
    

A simple use case using the CMake file name and the global target:

# ...
find_package(optional-lite REQUIRED)
# ...
target_link_libraries(YOUR_TARGET nonstd::optional-lite)

These are all the available headers. Some of these ones might be non-public; make sure of it by visiting the optional-lite homepage listed above:

#include "nonstd/optional.hpp"
