我正在研究A makefile config类型。首先，我ran nmake 命令认为它可能会告诉我文件在哪里，但是我有一个错误： nmake：致命错误u1064：找不到makefile且未找到目标> ，我认为没有一个，我必须做到这一点。因此，我制作了一个文件并将其命名为 makefile ，在内部我只添加了一行 jnilib = c：\ program Files \ java \ jdk1.8.0_333 \ lib \ lib \ jvm.lib 我以为我需要。之后，我再次运行 nmake ，只有这次我回来了：
Microsoft (R) Program Maintenance Utility Version 14.29.30141.0

但是问题仍然存在，那是错误lnk2019未解决的外部符号。这意味着我做错了什么，但是老实说，我不知道如何使用 makefile 清楚地显示出来（也许我需要在文件中添加更多，或者我写的错误是错误的） 。
谁能帮我克服这个错误？那是我唯一的问题，如何告诉它我正在从该位置使用该库。
I was working on a tutorial project I found on another website where it explains how to use Java inside a C++ project (this is just for context, isn't the important part). The project was working as it should. After that I wanted to copy the code to another project, but this time it was of Makefile config type. First I ran nmake command thinking that it might tell me where the file is, but I got an error instead: NMAKE : fatal error U1064: MAKEFILE not found and no target specified, which I thought that there isn't one, and I have to make it. So I made a file and named it Makefile and inside I added only one line JNILIB=C:\Program Files\Java\jdk1.8.0_333\lib\jvm.lib that I thought I need. After that I ran nmake again, only this time I got back:
Microsoft (R) Program Maintenance Utility Version 14.29.30141.0

But the problem still persists and that is Error LNK2019 unresolved external symbol. This means I'm doing something wrong, but to be honest I don't know how to use Makefile which clearly shows (maybe I need to add more to the file, or what I wrote is wrong).
Can anyone help me get past this error? That is the only problem I have, how to tell it that I'm using that library from that location.

我不熟悉使用
nmake。以下是我进行的测试，将DLL与CPP相同的目录。makefile：
I am not familiar with using
nmake. Below is a test I did, putting the DLL in the same directory as cpp.makefile:
