Can not compile the tests, on Mac Big Sur, clang v12, CMake 3.19.1, boost v1.74.0

Can not compile on Mac Big Sur, clang v12, CMake 3.19.1
I tried to fix it, but i failed.
The document should update:

 cmake -Bbuild -DQUANTUM_ENABLE_TESTS=ON   .
-- CMAKE_CXX_FLAGS = -Wall -Wextra -O0 -m64 -std=c++17 -ftemplate-backtrace-limit=0 -faligned-new
-- Doxygen configuration files have not been generated. Use QUANTUM_BUILD_DOC=ON to generate them.
-- Boost include dir: /usr/local/include
-- Boost library dir: /usr/local/lib
-- Boost use static libs: ON
-- Boost is multi-threaded: ON
-- Boost libraries: Boost::context

-- CMAKE_INSTALL_PREFIX = /usr/local

-- BOOST_ROOT =
-- REQUIRED BOOST_VERSION = 1.61
-- GTEST_ROOT =
-- Configuring done
-- Generating done
-- Build files have been written to: /Users/kyle/projects/quantum/build

and I use the "fixed" make test command here :

make QuantumTests && ctest 

and I got those errors:

[ 16%] Building CXX object tests/CMakeFiles/QuantumTests.dir/quantum_coro_ranges_tests.cpp.o

      namespace 'std'
    _control(std::reinterpret_pointer_cast<Control>(other._control))

maybe the wrong cxx flags ?
but i confirmed that CMAKE_CXX_FLAGS has -std=c++17

@kylelee Sorry just saw this. Did you manage to get this working? I can take a look otherwise...

Have the same issue on Catalina. std::reinterpret_pointer_cast is a C++20 feature and missing on Apple clang.

no template named 'reinterpret_pointer_cast' in namespace 'std'; did you mean 'boost::reinterpret_pointer_cast'?
