cmake - 为什么“target_link_libraries”命令不起作用？（复杂）

Question

我尝试使用 cmake 命令编译一个项目（所有实现都是由其他人编写的。我的工作只是编译和运行。）

cmake 后的错误信息

这是cpxutils/CMakeLists.txt 文件。

我不知道为什么尽管找到了 CPLEX 包却找不到目标。

我正在使用 WSL1 (Ubuntu) 环境。↑ 问题解决了。感谢@Tsyvarev。

=== 附加问题 ===

即使 cmake commad 没有任何错误，我也找不到执行文件。所以我检查了'CMakeError.log'文件，然后有一些错误。

这是 CMakeError.log 文件。

Source file was:
#include <pthread.h>

void* test_func(void* data)

  return data;
}

int main(void)

  pthread_t thread;
  pthread_create(&thread, NULL, test_func, NULL);

我认为这就是为什么我找不到执行文件的原因。但我不知道为什么尽管 pthread 库安装良好，但仍会出现此错误...
