有关LNK2019、LNK2001 和 LNK1120 错误的可能原因和解决方案的详细信息,请参阅 Stack Overflow 问题:What is an undefined reference/unresolved external symbol error and how do I fix it?。
error LNK2019:unresolved external symbol 这个错误是指程序不认识函数。具体的说就是.h文件中定义并没有实现,这就是库出现了问题。 遇到这个问题,第一步就要看是哪个函数,然后这个函数用的是哪个库,添加库,并写好库的路径就没问题了。如下图:

but whatever I try I get the unresolved external symbol error. In the other programs that use this module I build a VS2019 project, but now I am building a simple program at the command line. (I suspect that I faced and solved this problem a few years ago, but now...
你在程序中调用的函数或使用的外部变量没有定义

不能解析的外部符号”究竟是什么，在你没有提供更具体的信息之前，只能有个建议性的回答：1，先确定unresolved external symbol是哪个函数或者变量的名字 2，如果它是函数名字，检查是否对头文件声明的函数进行了实现。3，如果它是变量名，这种问题一般出在头文件声明了静态变量，需要在cpp中进行初始化。
