cmake error

[jrsims2]

Really appreciate running across your code. Very new to coding. When I followed your steps I got this error

Defaulting PICO_PLATFORM to rp2040 since not specified.

the compiler, or to the compiler name if it is in the PATH.

This error occurs because fullPathToCompiler has to be changed to the compiler's path.
With your current setup, you should run the following command:

cmake -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE -DCMAKE_C_COMPILER:FILEPATH="/usr/bin/arm-none-eabi-gcc" -DCMAKE_CXX_COMPILER:FILEPATH="/usr/bin/arm-none-eabi-g++" ..

On a related note, I just committed some changes to this repo that make it more clear how to use this project.
Assuming you want to test the thermal camera's functionality you'll want to compile and run the sample code as described in the README.md.
And eventually if you choose to use this code in a project, you might want to check out the ThermalCamera.h header only library as it provides an easy to use wrapper over the API.

I hope this helps.
