LNK2019:未解析的外部符号(Qt+cplex）

我正在Qt中制作一个简单的控制台应用程序（Qt Creator 3.3.2（开源）基于Qt 5.4.1（MSVC 2010，32位），它使用cplex（12.3.0.0）。代码看起来像：

这是一个简单的分配模型。在构建时，我得到32个错误，如：

main.obj:-1:错误：LNK2019:未解析的外部符号"public：double __thiscall IloAlgorithm:：getObjValue（void）const"（？getObjValue@IloAlgorithm@@QBENXZ）在函数_main 中引用

我已经清理、关闭、重新启动、再次运行qmake并重建。。。但仍然是同样的错误。。。
