Add one more variable in ROOT 7 build command - - on this page a command is given to help build root 7, it should be slightly modified as, it is not building root 7 experimental files properly.
I found this command working

cmake -DCMAKE_CXX_STANDARD=14 - DROOT7=True path/to/root/source

Instead of this command
cmake -DCMAKE_CXX_STANDARD=14 path/to/root/source.

Hi @rudradesai200,
welcome to the ROOT forum and sorry for the delay.
@amadio or @Axel might know whether -DCMAKE_CXX_STANDARD=14 should set -DROOT7=True (like the docs seem to imply) or it is required to specify it explicitly.

You don’t need -DROOT7=true, the option is called -Droot7=True and gets enabled by default when you use C++14 and above (which is a requirement to enable it).
