cmake ../ -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_FLAGS="-Ofast -DNDEBUG -mcpu=cortex-a72"

This should be

cmake .  -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_FLAGS="-Ofast -DNDEBUG -mcpu=cortex-a72"

@mitu what does changing cmake ../ to cmake . do?

i have been using cmake ../ without a problem inn my script.

im learning which is why im asking

@exarkuniv When you run cmake, you'll have to point it at the folder containing the CMakeFiles.txt file. If you run it from the projects's source folder and you point to .., then cmake looks for the file in the parent folder (/home/pi) - but in the error above there's no such file there.
If you run it from a build subfolder inside the main project folder, then it's ok to point cmake to .., since this is where CMakeFiles.txt is located, i.e.

git clone <a_cmake_based_project>
cd <a_cmake_based_project>
mkdir build 
cd build
cmake .. <OTHER_CMAKE_ARGS>

@mitu ok. thank you for clearing that up.
taking a look at my script i was doing it right since i was running cmake inside of my build subfolder.

Thanks I was able to get past that and now am getting

error "Unsupported version of nlohmann json library, must be >= 3.6"

@musicislife6984 did you install all of the dependencies that quicksilver has.

and it just might be easier to just use the script i have made to do all the work for you. it is a few posts above

@exarkuniv How do I execute your script?

ExarKunIv

@musicislife6984

run

wget https://raw.githubusercontent.com/Exarkuniv/-RollerCoaster-Tycoon-2-port/Master/openrct.sh -P $HOME/RetroPie-Setup/scriptmodules/ports/

in the command line, after that you just need to find openrct in the experimental list within the RetroPie setup menu

like you would to install anything extra

@quicksilver @hooperre I've got to the 4th part of step 3 (make -j4) but am blocked by the following error. Any guess why?

fatal error: nlohmann/json_fwd.hpp: No such file or directory
12 | #include <nlohmann/json_fwd.hpp>

@evansauve I would check out @ExarKunIv awesome archive of extra games for retropie. He has a script already setup to install this game without having to do everything manually.

https://github.com/Exarkuniv/RetroPie-Extra

Follow the instructions on there and then you should be able to install openrct2 right through the retropie menu
