+Boost libraries are needed, so you can install them using nuget:
+```
+nuget install boost_chrono-vc142 -Version 1.77.0
+nuget install boost_system-vc142 -Version 1.77.0
+nuget install boost -Version 1.77.0
+```
+To build and install succesfully, [rabbitmq-c](https://github.com/alanxz/rabbitmq-c) should be built **as shared library**.
+
+Let *boost_chrono* and *boost_system* be in same directory ```C:\boost```, [rabbitmq-c](https://github.com/alanxz/rabbitmq-c) be on ```C:\rabbitmq-c```,
+SSL be OFF, and VS2019 is used, than CMake CLI is:
+```
+cd cmake -G "Visual Studio 16" -A x64 -DBoost_INCLUDE_DIR="C:/boost.XX.XX.X.X/lib/native/include" -DBOOST_ROOT="C:/boost.X.XX.X.X" -DBOOST_LIBRARYDIR="C:/boost" -DRabbitmqc_INCLUDE_DIR="C:/rabbitmq-c/include" -DRabbitmqc_LIBRARY="C:/rabbitmq-c/lib/rabbitmq.4.lib" -DBoost_USE_STATIC_LIBS=ON -DBUILD_STATIC_LIBS=ON -DENABLE_SSL_SUPPORT=OFF ..
