[BUG] Installation fails with "error: cmd has incomplete type" in inverter.cpp

[csabo80]

Hello,
I am trying to install the addon (EASUN inverter), but the installation fails during the build process with a compilation error.
It seems like there is an issue with the C++ source code in the 'inverter-cli' part of the build.
Here are the exact error logs from my Home Assistant Supervisor log:
6.081 /opt/inverter-cli/inverter.cpp: At global scope:

ERROR: failed to build: failed to solve: process "/bin/bash -o pipefail -c cd /opt/inverter-cli && mkdir bin && cmake && make && mv inverter-poller bin/" did not complete successfully: exit code: 2
Could you please look into this issue? Thank you for your work on this addon!
