Regarding integration of NURAN L1 1.0

Hello, We are starting to integrate and test NURAN L1 1.0 with osmo-bts / osmo-pcu at Radisys. We downloaded latest osmo-bts master branch. When we checked the code, we see that NURAN specific code is present in osmo-bts/src/osmo-bts-litecell15. When we tried to compile osmo-bts/src/osmo-bts-litecell15 , we see the following error nrw/litecell15/litecell15.h: No such file or directory Let us know if these files are missing or we are missing some steps. Thanks and regards Prasad
