我在UBUNTU 18.04 下用CUDA 10.2 和 C++11标准编译一个较大的工程。 Makefile 是用CMAKE文件生成的。当我在terminal完成编译时显示了如下错误：
/usr/bin/ld: cannot find -lOPTIONS
collect2: error: ld returned 1 exit status
CMakeFiles/cuda_othermain.dir/build.make:132: recipe for target 'bin/cuda_othermain' failed
make[2]: *** [bin/cuda_othermain] Error 1
CMakeFiles/Makefile2:79: recipe for target 'CMakeFiles/cuda_othermain.dir/all' failed
make[1]: *** [CMakeFiles/cuda_othermain.dir/all] Error 2
Makefile:83: recipe for target 'all' failed
make: *** [all] Error 2
提示是找不到一个叫OPTIONS的库。我的camke和源码里都没有链接这个库，而且我在网上搜索也根本没有一个库叫做OPTIONS。我很疑惑，编译工程时没有显示任何其他错误，顶多就是有几个warning，我查了一下都是没有太大关系的。所以现在没有什么思路去解决这个问题。 所以想请教一下各位有没有什么解决思路。 CMAKE文件如下：

源代码就没发帖了，因为工程还算比较大。有劳各位了。
