compilation error pc-ble-driver on ubuntu

[Mukul]

I downloaded the pc-ble-driver from github. I am using NRF52840 devKit and ubuntu 18.0 x86 machine. While compiling pc-ble-driver, I hit the following issue:
Can someone pls help with this issue ? Cmake version is 3.14.1

mukul@soumya-SH370:~/nordic/nordic-driver/pc-ble-driver-master/build$ cmake -G Ninja ..
-- NRF_BLE_DRIVER_VERSION not specified, setting it to 0.0.0
CMake Error: CMake was unable to find a build program corresponding to "Ninja".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

I was able to compile pc-ble-driver after installing ninja-build via "apt-get install ninja-build" and adding mergehex to PATH variable.
