            You are following the method signature to CMake helper imported directly from conans. However, you imported the new CMake helper designed to Conan 2.0. They are incompatible.

            You can keep the new helper, but you need to define your generator in conanbuild.conf. (Yet not documented)

            However, you also can set it directly in your CMakeToolchain constructor:

            You use the wrong source for showing the selected item. As the shortened list is not the same as adfl, you should not use adfl inside sauthor_list(). You need to get the selected item using frame1_lb.get() instead:

            How to propagate conan's compiler.cppstd setting to the compiler when building a library with CMake?
            Asked 2022-Feb-17 at 14:15

            If you build a library with conan and set compiler.cppstd setting to e.g. 20 and call conan install, the libraries are still built with the default standard for the given compiler.

            The docs say:

            The value of compiler.cppstd provided by the consumer is used by the build helpers:

            • The CMake build helper will set the CONAN_CMAKE_CXX_STANDARD and CONAN_CMAKE_CXX_EXTENSIONS definitions that will be converted to the corresponding CMake variables to activate the standard automatically with the conan_basic_setup() macro.

            So it looks like you need to call conan_basic_setup() to activate this setting. But how do I call it? By patching a library's CMakeLists.txt? I sure don't want to do that just to have the proper standard version used. I can see some recipes that manually set the CMake definition based on the setting, e.g.:

            But this feels like a hack either. So what is the proper way to make sure libraries are built with the compiler.cppstd I specified?

            Answered 2022-Feb-17 at 14:15

            Avoid patching, it's ugly and fragile, for each new release you will need an update due upstream's changes.

            The main approach is a CMakeLists.txt as wrapper, as real example: https://github.com/conan-io/conan-center-index/blob/5f77986125ee05c4833b0946589b03b751bf634a/recipes/proposal/all/CMakeLists.txt and there many others.

            Try specify instead -Dbuild.pkg_config_path=... from this

            Since 0.51.0, some options are specified per machine rather than globally for all machine configurations. Prefixing the option with build. just affects the build machine configuration...

            build.pkg_config_path controls the paths pkg-config will search for just native: true dependencies (build machine).

            PS, the version of meson and that you have native build I deduced from your previous question ;)

            I have used pybind in the past (two or three years ago) and it worked without problems with conan. However, I tried to install it now and faced similar problems. This might be related to the evolution of conan towards conan 2.0 (an alpha version was released today) and that the recipe was not updated to account changes.

            An alternative that you might consider, is to install pybind with conan using a different generator. More specifically, the CMakeDeps generator. With the CMakeDeps generator conan will create a pybind11-config.cmake file for you and you just need to use find_package(pybind11 REQUIRED) in CMakeLists.txt. That is, there is no "conan specific stuff" in your CMakeLists.txt file.

            By default a lambda's call operator is const-qualified.

            Inside the lambda's body the this pointer to the lambda is therefore also const-qualified and so is the member wrapper. std::packaged_task does not have a const-qualified operator(), so it cannot be called.

            You can make the lambda's operator() non-const-qualified by adding the mutable keyword:
