Hi!
<br>
If you really are using openlp-master (which I'm reluctant to recommend at the moment), the easiest way to generate a build is to push your customizations to a Pull Request on GitLab, but in the appveyor.yml file, look for FORCE_PACKAGING and change its value to 1 in the appropriate section (win-x86 vs win-x64 vs MacOs).
This will make the CI system build the Pull Request with installers. Note that all tests must pass (unless you disable the test run in appveyor.yml as well).
You can click through the pipeline links to find the builds, or look here: https://ci.appveyor.com/project/OpenLP/openlp-u6hnj/history<br></div><div>I hope this makes sense! Best of luck :)<br>
