Cannot find engine folder in ISaac 2020

I cannot find engine folder in new Isaac. How to install dependency?
I used engine from 2019 but the bazel 4.0.0 cannot compile.
I got this error:

ERROR: /home/comm/.cache/bazel/_bazel_comm/6c4be63dbe8a1a11d0919f74c2542115/external/com_nvidia_isaac_engine/engine/alice/tools/BUILD:48:16: Compiling engine/alice/tools/main.cpp failed: undeclared inclusion(s) in rule ‘@com_nvidia_isaac_engine//engine/alice/tools:main’:

I am new to bazel.
Please suggest. Thanks.
