Install higher version cmake firstly:

jshi19@ub2-uefi-b01:~$ git clone https://github.com/Kitware/CMake.git
jshi19@ub2-uefi-b01:~/CMake$ git checkout v3.17.2
jshi19@ub2-uefi-b01:~/CMake$ ./bootstrap --parallel=5
jshi19@ub2-uefi-b01:~/CMake$ make -j 5
jshi19@ub2-uefi-b01:~/CMake$ sudo make install

Install SDK

jshi19@ub2-uefi-b01:~$ wget https://github.com/zephyrproject-rtos/sdk-ng/releases/download/v0.11.3/zephyr-sdk-0.11.3-setup.run
jshi19@ub2-uefi-b01:~$ chmod +x zephyr-sdk-0.11.3-setup.run
jshi19@ub2-uefi-b01:~$ ./zephyr-sdk-0.11.3-setup.run -- -d ~/zephyr-sdk-0.11.3

Build reel_board example

jshi19@ub2-uefi-b01:~$ cd zephyrproject/zephyr/
jshi19@ub2-uefi-b01:~/zephyrproject/zephyr$ west build -p auto -b reel_board samples/basic/blinky
