There is no versionning for KTccminer so feel free to place it wherever you want
We do not understand each other or you do it on purpose. I expect not.
I will rewrite what you should have proposed:
mkdir -p /home/m1/Downloads/miners/KTccminer
cd /home/m1/Downloads/miners/KTccminer
wget https://github.com/KlausT/ccminer/archive/windows.zip
unzip windows.zip
cd ccminer-windows
./build.sh
mv -R ccminer /home/m1/KTccminer
Do you understand that there is
no -8.18 behind the name of your KTccminer directory?
Just KTccminer and nothing else!
Do it on your machine if you want, but for reasons of simplification of nvOC management, your proposal is malformed.
In addition I wonder with your link that seems to indicate that it is a
windows version, while nvOC works with Ubuntu, itself a branch of
Debian LINUX
