  1. When compiling the nmos cpp source code using cmake on Ubuntu 22.04 system, the following error occurs:

CMake Error: CMAKE_PROJECT_TOP_LEVEL_INCLUDES file does not exist: third_party/cmake/conan_provider.cmake
CMake Error at CMakeLists.txt:16 (enable_language):
Language 'CXX' is currently being enabled. Recursive call not allowed.

-- Configuring incomplete, errors occurred!
See also "/home/gule/nmos-cpp/Development/CMakeFiles/CMakeOutput.log".

2 The configuration of the cmake configuration file CMakeLists.txt is as follows:

# the injection point may be used to configure conan, but that requires CMake 3.24 or higher
# so avoid confusion and reject invocations which attempt to use it on lower versions
# see https://cmake.org/cmake/help/v3.24/variable/CMAKE_PROJECT_TOP_LEVEL_INCLUDES.html
# the alternative is to run conan install first instead
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/Development/cmake")

if(CMAKE_PROJECT_TOP_LEVEL_INCLUDES)
  cmake_minimum_required(VERSION 3.24 FATAL_ERROR)
    else()
       cmake_minimum_required(VERSION 3.17 FATAL_ERROR)
    endif()
    #cmake_minimum_required(VERSION 3.17 FATAL_ERROR)
# project name
project(nmos-cpp)

enable_language(CXX)
# enable or disable the example applications
set(NMOS_CPP_BUILD_EXAMPLES ON CACHE BOOL "Build example applications")

# enable or disable the unit test suite
set(NMOS_CPP_BUILD_TESTS ON CACHE BOOL "Build test suite application")

# enable or disable the LLDP support library (lldp)
# and its additional dependencies
set(NMOS_CPP_BUILD_LLDP OFF CACHE BOOL "Build LLDP support library")
mark_as_advanced(FORCE NMOS_CPP_BUILD_LLDP)

# common config
include(${CMAKE_SOURCE_DIR}/Development/cmake/NmosCppCommon.cmake)

# nmos-cpp dependencies
include(${CMAKE_SOURCE_DIR}/Development/cmake/NmosCppDependencies.cmake)

# nmos-cpp libraries
include(${CMAKE_SOURCE_DIR}/Development/cmake/NmosCppLibraries.cmake)

if(NMOS_CPP_BUILD_EXAMPLES)
    # nmos-cpp-node executable
    include(${CMAKE_SOURCE_DIR}/Development/cmake/NmosCppNode.cmake)

    # nmos-cpp-registry executable
    include(${CMAKE_SOURCE_DIR}/Development/cmake/NmosCppRegistry.cmake)
endif()

if(NMOS_CPP_BUILD_TESTS)
    # nmos-cpp-test executable
    include(${CMAKE_SOURCE_DIR}/Development/cmake/NmosCppTest.cmake)
endif()

# export the config-file package
include(${CMAKE_SOURCE_DIR}/Development/cmake/NmosCppExports.cmake)

Can you give me some advice?

    It seems that CMake is not finding the conan_provider.cmake file.

    You could verify that it is in the file system; it should be found in the Development\third_party\cmake directory.

    Then make sure that CMake is being run from the correct directory as per the Getting Started instructions:

    cd <home-dir>/nmos-cpp/Development
mkdir build
cd build
cmake .. \
  -DCMAKE_BUILD_TYPE:STRING="<Debug-or-Release>" \
  -DCMAKE_PROJECT_TOP_LEVEL_INCLUDES:STRING="third_party/cmake/conan_provider.cmake"
make

    Thank you very much for your suggestion

According to your suggestion 

    > cd <home-dir>/nmos-cpp/Development
> mkdir build
> cd build
> cmake .. \
>   -DCMAKE_BUILD_TYPE:STRING="<Debug-or-Release>" \
>   -DCMAKE_PROJECT_TOP_LEVEL_INCLUDES:STRING="third_party/cmake/conan_provider.cmake"
> make

    Use the following instructions to perform compilation, but the result is as follows

    CMake Error: CMAKE_PROJECT_TOP_LEVEL_INCLUDES file does not exist: third_party/cmake/conan_provider.cmake
CMake Error at CMakeLists.txt:30 (enable_language):
  Language 'CXX' is currently being enabled.  Recursive call not allowed.

See also "/home/gule/nmos-cpp/Development/CMakeFiles/CMakeOutput.log".

    But there is indeed conad_vider.cmake in the Development/cmake folder

     Here are the contents of the cmake folder

    gule@gule-VirtualBox:/nmos-cpp/Development/cmake$ ls
    CMakeRegexEscape.cmake NmosCppCompileSettings.cmake NmosCppExports.cmake NmosCppRegistry.cmake
    conan_provider.cmake nmos-cpp-config.cmake.in NmosCppLibraries.cmake NmosCppTest.cmake
    NmosCppCommon.cmake NmosCppDependencies.cmake NmosCppNode.cmake
    gule@gule-VirtualBox:    /nmos-cpp/Development/cmake$ pwd
    /home/gule/nmos-cpp/Development/cmake

    What a headache inducing problem

    The location of your conan_provider.cmake file is incorrect for some reason.

    CMake expects it to be in the relative location third_party/cmake/conan_provider.cmake which you'll see from the error message you're getting.

    The absolute location for you would therefore be ~/nmos-cpp/Development/third_party/cmake/conan_provider.cmake and not in ~/nmos-cpp/Development/cmake/conan_provider.cmake where you seem to have it.
