CMake Error at src/CMakeLists.txt:169 (find_package):
  By not providing "Findasio.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "asio", but
  CMake did not find one.

  Could not find a package configuration file provided by "asio" with any of
  the following names:

    asioConfig.cmake
    asio-config.cmake

  Add the installation prefix of "asio" to CMAKE_PREFIX_PATH or set
  "asio_DIR" to a directory containing one of the above files.  If "asio"
  provides a separate development package or SDK, be sure it has been
  installed.

@paulocoutinhox Did you install the asio lib? We don't have a MacOs environment so there may be errors in the compilation.

Could you join this discord group and call me? https://discordapp.com/invite/3NxYnyV

Apparently the asio lib not found, or you didn't install it correctly, or on the mac you need some other dependency to link, it's complicated for us to help because we don't have an environment to test, try to search a little on Google and see what it can be. You can also try using docker instead of clang.

The asio is installed, but don't have a FindASIO.cmake. I created one:

set(ASIO_FOUND FALSE)

if(TARGET ASIO::ASIO)
  set(ASIO_FOUND TRUE)
else()
  find_package(Threads QUIET)
  if(NOT Threads_FOUND)
    if(ASIO_FIND_REQUIRED)
      message(FATAL_ERROR "ASIO requires thread support, but it wasn't found.")
    else()
      if(ASIO_FIND_QUIETLY)
        message(STATUS "ASIO requires thread support, but it wasn't found.")
      endif()
    endif()
  else()
    find_path(ASIO_ROOT include/asio.hpp
      PATHS
        # Where asio lives relative to it's official repository
        ${CMAKE_CURRENT_LIST_DIR}/../../asio/asio

        # Where asio should live
        ${CMAKE_CURRENT_LIST_DIR}/../../asio
    )
    if(NOT ASIO_ROOT)
      if(ASIO_FIND_REQUIRED)
        message(FATAL_ERROR "ASIO headers could not be found.")
      else()
        if(ASIO_FIND_QUIETLY)
          message(STATUS "ASIO headers could not be found.")
        endif()
      endif()
    else()
      add_library(ASIO::ASIO INTERFACE IMPORTED GLOBAL)
      set_target_properties(ASIO::ASIO PROPERTIES
        INTERFACE_COMPILE_DEFINITIONS "ASIO_STANDALONE"
        INTERFACE_INCLUDE_DIRECTORIES "${ASIO_ROOT}/include"
      )
      target_link_libraries(ASIO::ASIO INTERFACE Threads::Threads)
      set(ASIO_FOUND TRUE)
    endif()
  endif()
endif()

For gcc and visual studio the lib is automatically targeted, probably not for clang.
Thanks for the feedback.

This issue is stale because it has been open 120 days with no activity.

currently the build for mac is working perfectly so i will be closing this issue.
