CMake Error

[IronBit-0]

Following this tutorial, I'm running into the error below after running cmake .. in owl/build.
I'm on a Raspberry Pi 3 Model B V1.2, and it's running Raspberry Pi OS Lite (32-Bit). I'm running cmake version 3.18.4.

root@raspberrypi:/home/pi/owl/build# cmake ..

I found a fix which is adding

set( CMAKE_CXX_COMPILER "/pathto/g++" )
set( CMAKE_C_COMPILER "/pathto/gcc" )

to the beginning of CMakeLists.txt, replacing the paths with the location of g++ and gcc, which for me was /usr/bin/g++ and /usr/bin/gcc. I found the paths using which g++ and which gcc. Found from this link.
