Need help setting up Dev environment on Debian 12.5 (Bookworm)

[jcarp-7ab]

I have downloaded the Tvision code and unzipped to tvision-master. I tried the cmake commands but it is not creating libtvision.a in the build directory.

Wait, I think I got it...

~/Dev/tvision-master$ cmake --build ./build
[ 0%] Building CXX object source/CMakeFiles/tvision.dir/cmake_pch.hxx.gch
[ 1%] Building CXX object source/CMakeFiles/tvision.dir/platform/ansiwrit.cpp.o
...
[ 90%] Building CXX object source/CMakeFiles/tvision.dir/tvision/twindow.cpp.o
[ 91%] Linking CXX static library ../libtvision.a

Yep, that did it...
cmake --build ./build

is the command that worked for me.
