linux 下编译报错：error while loading shared libraries: libmkl_intel_lp64.so: cannot open shared object file

参考：https://blog.csdn.net/liu_feng_zi_/article/details/107434052
原理大概是 ldconfig 给制造了软链接，所以需要哪个库，就去找：
sudo find / -maxdepth 10 -name libmkl_intel_lp64.so
找到以后把它的目录写进 /etc/ld.so.conf.d/mkl.conf
然后 ldconfig
