Running a build with a newer CMake version results in a deprecation
warning from the tools subdirectory
[13/108] Performing configure step for 'PioasmBuild'
loading initial cache file /.../build/pico-sdk/src/rp2_common/pico_cyw43_driver/pioasm/tmp/PioasmBuild-cache-Release.cmake
CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
Compatibility with CMake < 3.5 will be removed from a future version of
CMake.
Update the VERSION argument <min> value or use a ...<max> suffix to tell
CMake that the project does not need compatibility with older versions.
Raise the minimum version requirement for the tools to the same version
that is required in the top-level CMakeLists.txt anyway.
While working on the [online pioasm](https://wokwi.com/tools/pioasm), I found several PIO instructions that result in invalid python code. Here is a small program that demonstrate the issue:
```
.program python_issue
push block
wait 0 irq 1 rel
irq clear 1 rel
```
And the resulting Python program:
```python
# -------------------------------------------------- #
# This file is autogenerated by pioasm; do not edit! #
# -------------------------------------------------- #
import rp2
from machine import Pin
# ----------- #
# python_test #
# ----------- #
@rp2.asm_pio()
def python_test():
wrap_target()
push(, block) # 0
wait(0, irq, 1 rel) # 1
irq(clear 1 rel) # 2
wrap()
```
After this fix, the above program compiles to a valid python syntax:
```python
# -------------------------------------------------- #
# This file is autogenerated by pioasm; do not edit! #
# -------------------------------------------------- #
import rp2
from machine import Pin
# ----------- #
# python_test #
# ----------- #
@rp2.asm_pio()
def python_test():
wrap_target()
push(block) # 0
wait(0, irq, rel(1)) # 1
irq(clear, rel(1)) # 2
wrap()
```
