Tried adding linux code to prepare GSPlus for RetroPie

[striderhiryux99]

Hello everyone. I tried following the steps to enter the linux code into the command prompt. I was able to reach the third line under the build section (cmake ..), but I receieved an error message:

CMake Error: The source directory "/home/pi" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.

Should I use additional commands to continue the build process? If I should stop at this point, are there any commands I may use to remove whatever has been installed? If the latter is true, where can I find the set of command lines that would allow me to install GSPlus for the RetroPie (on the Pi4B+)?

Thanks for your assistance.

Sorry this is months late. Pi user here. It looks like you didn't change your working directory to build. That's why it's attempting to search in your home dir. The working directory should be as follows: /home/pi/gsplus/build. Once you're there, run cmake ..
