No rule to make target 'external/src/libdwarf-project-install/lib/libretdec-libdwarf.so'

Hi I'm porting the tool to Pentoo Linux and facing this problem. I configured the tool using ```-DCMAKE_INSTALL_PREFIX="/opt"``` parameter and compiled it using the similar command:
```cmake .. -DCMAKE_INSTALL_PREFIX="/opt"``` as per documentation.

However, the installation fails with the following error:

```

Any ideas what's wrong?
