Hi Boost,
i read here [1] that boost::mqtt5 needs boost 1.82.0 but it is published with 1.88.0 Beta1
How to use boost::mqtt5 with boost 1.82.0?
Looking at their CMakeLists.txt file here: mqtt5/CMakeLists.txt at develop · boostorg/mqtt5 <https://github.com/boostorg/mqtt5/blob/develop/CMakeLists.txt> It seems like the easiest thing to do is just clone it into the Boost tree and treat it like any other library from there. Unless I'm misreading, it doesn't seem like this library is meant to be installed by CMake on its own. It only has two modes: I'm a boost.mqtt developer or I'm going to install this via BoostRoot.cmake. Haven't tested it locally but if you clone it into a 1.82 tree, you should be able to: cmake -DBOOST_INCLUDE_LIBRARIES=mqtt5 -DCMAKE_INSTALL_PREFIX=_install .. && cmake --build . --target install -j20 - Christian
