As Samuel Beckett said
try again, fail again, fail better
1- ATmega328P or any other chip
2- AVR Programmer *USBASP, AVR ISP etc.
3- Lot of jumper you'll need more in time
4- LED
5- Multimeter
6- Resistor
You don't need an external oscillator since you already have an internal one
1- You need an AVR cross-compiler avr-gcc, win-avr etc.
2- You need avrdude or any other uploader
3- You may or not use avr-objdump
avrdude: verification error, first mismatch at byte...
this may happen because you buy cheap USBASP. Thus it supplies only 3.3V, your chip not gonna work properly
avrdude: initialization failed, rc=-1
That means your programmer and chip cannot communicate with each other, so you better check your connections again
1- Go into /build folder
2- Run cmake ..
3- Run make
-Check your connections before you move on to the circuit
-You don't have to set your fuses you can use default fuses
-Don't just assign binary values to registers. Use masking and bit shifting

1- flash command doesn't work (SOLVED by adding avrdude config file)
