make failed during installation of Qtmqtt
-
You get the dev branch which is target to Qt 6 and Qt 6 moved to cmake.
Checkout the branch / tag that matches the Qt version you want to use in order to build the module.
-
As I wrote just above, checkout the 5.12.8 tag and follow the usual procedure.
-
git checkout 5.12.8Or
git switch 5.12.8Depending on the version you use.

Hello @SGaist , its throw an error after checkout the branch
root@latitude:/home/oem/Qt/5.15.2/gcc_64/lib/qtmqtt# git checkout 5.15.2
Already on '5.15.2'
Your branch is up to date with 'origin/5.15.2'.

You wrote that you needed that for Qt 5.12.8 so why is it now 5.15.2 ?
How did you install it ?
Why are you using your distribution provided qmake ?
If you want to build with your distribution provided Qt, you have to install the Qt "private" development packages from your distribution.If you want to build with a custom installed Qt, use the full path to the qmake executable you want to use.
Finally: stop doing stuff a root. There's no need for that especially when building libraries and whatnot. Use of root is only for machine management, not development.

Hii @SGaist , my system was got crashed , now i am installing mqtt library again but it's gives error please help me
I'm follow these steps :

You are using your distribution provided Qt. You need to install the Qt private development packages. The one for qtbase should be enough.
