[SKiDL BUG] ERROR: No footprint for GND/#PWR1.

[mooko-dev]

Describe the bug
Running the example code from the skidl's readme causes the following error:

ERROR: No footprint for GND/#PWR1. @ [.../skidltest.py:28]
ERROR: No footprint for VCC/#PWR2. @ [.../skidltest.py:28]
ERROR: No footprint for Q_PNP_CBE/Q1. @ [.../skidltest.py:28]
ERROR: No footprint for Q_PNP_CBE/Q2. @ [.../skidltest.py:28]
ERROR: No footprint for R/R1. @ [.../skidltest.py:28]
ERROR: No footprint for R/R2. @ [.../skidltest.py:28]
ERROR: No footprint for R/R3. @ [.../skidltest.py:28]
ERROR: No footprint for R/R4. @ [.../skidltest.py:28]
ERROR: No footprint for R/R5. @ [.../skidltest.py:28]

0 warnings found while generating netlist.
9 errors found while generating netlist.

I also tried to run the following code:

from skidl import *

set_default_tool(KICAD)
lib_search_paths[KICAD].append('/usr/share/kicad/symbols')
footprint_search_paths[KICAD].append('/usr/share/kicad/footprints')

# Create part templates.
q = Part("Device", "Q_PNP_CBE", dest=TEMPLATE)
r = Part("Device", "R", dest=TEMPLATE)

# Create nets.
gnd, vcc = Net("GND"), Net("VCC")
a, b, a_and_b = Net("A"), Net("B"), Net("A_AND_B")

# Instantiate parts.
gndt = Part("power", "GND")             # Ground terminal.
vcct = Part("power", "VCC")             # Power terminal.
q1, q2 = q(2)                           # Two transistors.
r1, r2, r3, r4, r5 = r(5, value="10K")  # Five 10K resistors.

# Make connections between parts.
a & r1 & q1["B C"] & r4 & q2["B C"] & a_and_b & r5 & gnd
b & r2 & q1["B"]
q1["C"] & r3 & gnd
vcc += q1["E"], q2["E"], vcct
gnd += gndt

generate_netlist()

It adds the footprint path to the search paths.
This code causes the same error.

To Reproduce
Steps to reproduce the behavior:

1. Create a python file containing the example code from the skidl readme
2. Set KICAD_SYMBOL_DIR to "/usr/share/kicad/symbols/"
3. Run python skidltest.py
4. See error

Desktop (please complete the following information):

• OS: Arch Linux 6.2.1-arch1-1
• Python version: 3.10.9
