This will roughly apply to Linux and Windows, but your mileage will vary.
I followed Rolf NooteBooms posts about using VSCode with the PSOC5 using the OneThinx setup. I was able to modify it to work with more of a standardized PSOC5 project, allowing you to switch from PSOC Creator to VSCode and back again. I keep a VM with the schematic up while I work on the code and debug on the Mac natively. (Also a few notes about Big Sur, which has made development jobs much harder.)
Once that worked, I was able to get it working with QT Creator. If you are interested, the setup information for all the above is on my blog at: https://socmaker.com/?p=1039
There is a series of 3 posts to read for the entire setup.
Enjoy!
