[Opm] Library dependency in building OPM

[LEI TING]

Hi, Marcus,
   Thanks for your reply. I'll try to explain what I did, and please find the attached 2 files from cmake.


   Since it's a remote server and I don't have root access, I use source codes of OPM to compile from source.
   For all dependencies, I use binary packages from the OPM site:  https://www.opm-project.org/package/redhat/7/, including dune, suitesparse, and trilinos.
   These 3 packages also depend on other packages, so I use yum to download all dependencies. I can't use 'yum install' because it requires root access. So I use yumdownloader to download all rpm packages, then use rpm2cpio and cpio to uncompress all the rpm packages to my home directory, like: rpm2cpio dune-common.rpm | cpio -div. 
   I guess maybe some packages depend on /usr/lib64/libopenblas.so. That is why cmake want to link with libopenblas.so. But I don't know which one depends on it and what I should do.
   I tried to modify the file build.make and link.txt to fix the path, like:
     origin:    bin/ebos: /usr/lib64/libopenblas.so
     fixed:     bin/ebos: /public/home/leiting/exec/usr/lib64/libopenblas.so
"/public/home/leiting/exec" is the folder I put all dependencies.
It can work, but every time I run cmake, I have to fix a lot of files. So I want to find a way to solve the problem. Or do you have a better way to compile the OPM source?
  Thanks again.
  
  Regards,
