# How to build ZMQ Libs:
# libzmq.lib, libzmq-d.lib, libzmq_64.lib, libzmq-d_64.lib, etc.
#
# git clone --branch v4.3.4 --depth 1 https://github.com/zeromq/libzmq.git
#
# mkdir libzmq\build32
# cmake -DCMAKE_BUILD_TYPE=Release -A Win32 -S libzmq -B "libzmq\build32" -DBUILD_TESTS=NO -DZMQ_BUILD_TESTS=NO -DENABLE_CURVE=NO -DWITH_TLS=NO
# cmake --build libzmq\build32 --config Debug
# cmake --build libzmq\build32 --config Release
#
# mkdir libzmq\build64
# cmake -DCMAKE_BUILD_TYPE=Release -A x64 -S libzmq -B "libzmq\build64" -DBUILD_TESTS=NO -DZMQ_BUILD_TESTS=NO -DENABLE_CURVE=NO -DWITH_TLS=NO
# cmake --build libzmq\build64 --config Debug
# cmake --build libzmq\build64 --config Release
#
# Libs and Dlls can be found in libzmq\build64\bin\<build_type> and libzmq\build64\lib\<build_type> etc.
#
# Copy and rename dlls:
# "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvars32.bat"
# python ..\..\..\tools\rename_dll.py .\libzmq-v143-mt-4_3_4.dll libzmq.dll x86
# python ..\..\..\tools\rename_dll.py .\libzmq-v143-mt-gd-4_3_4.dll libzmq-d.dll x86
#
# "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvars64.bat"
# python ..\..\..\tools\rename_dll.py .\libzmq-v143-mt-4_3_4.dll libzmq_64.dll x64
# python ..\..\..\tools\rename_dll.py .\libzmq-v143-mt-gd-4_3_4.dll libzmq-d_64.dll x64
#
# Also, if you're updating the libs, you should update cppzmq (zmq.hpp and zmq_addon.hpp)
# https://github.com/zeromq/cppzmq
#
# TEST AND MAKE SURE THAT EVERYTHING STILL WORKS!
