如何将boost库链接为动态库而不是vcpkg中的static

Question

I'm using VS 2019 with vcpkg and boost 1.81

I've created a Dynamic Link Library Project (c++) and I've added the boost serialization library headers.

when I set vcpkg to use static libraries it builds fine, however if i set the "Use static Libraries" to No then I get the following compiler errors

Severity    Code    Description Project File    Line    Suppression State

what should i do to get it to build as a dynamic library?

UPDATE 2023/1/30 this issue happens only when adding the portable_binary_iarchive and portable_binary_iarchive files to the project. these files are not part of the standard boost library, however they are included in the examples.

you can create a CMake project, add the following commond in your CMakeLists.txt :

set(Boost_USE_STATIC_LIBS OFF)
