@Rohith Add -v parameter to your configure call and see what is missing.
As explained here https://doc.qt.io/qt-5.10/qtbluetooth-index.html you probably do not have BlueZ (dev package inclusive) installed on your system.

Rohith

@jsulm

Thanks for replying..!

I have checked in system by the help of command "bluetoothctl --version"

It showed version 5.36 was installed in my system.

@Rohith You need BlueZ dev package installed as I said, else it will not work (it doesn't matter what "bluetoothctl --version" returns as long as the BlueZ header files are missing). Did you try to add -v to see what exactly is missing?

Checking for BlueZ... 
Trying source 0 (type pkgConfig) of library bluez ...
+ /usr/bin/pkg-config --exists --silence-errors bluez
pkg-config did not find package.
  => source produced no result.

Here is what i found after giving -v while configuring.

@Rohith said in How to enable support of QtBluetooth..?:

bluetooth/bluetooth.h

As you can see the header files are missing.
You need to install libbluetooth-dev package (on Ubuntu/Debian, if you're using a different distribution the name can be different).

@jsulm

Thanks @jsulm it worked after installing dnf install bluez-libs-devel for my fedora.
