[cpp-base64] base64.cpp linker error

[BullyWiiPlaza]

Describe the bug Why do I get a linker error with the base64.cpp file of this library? With other libraries I don't need to manually add a *.cpp file to my project. A workaround is Add -> Existing Item... in Visual Studio.

Environment

• OS: Windows 11 Pro
• Compiler: Microsoft (R) C/C++ Optimizing Compiler Version 19.32.31332 for x64

To Reproduce Steps to reproduce the behavior:

1. vcpkg install cpp-base64:x64-windows
2. Add #include <cpp-base64/base64.h> to the top of a source file and call base64_encode() somewhere in your code.
3. Compile and observe the linker error occurring:

LNK2019	unresolved external symbol "class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > __cdecl base64_encode(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &,bool)" (?base64_encode@@YA?AV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@AEBV12@_N@Z) referenced in function [...]

Expected behavior Including the header and compiling will work with no further action required by the developer just like how almost all other ports behave.
