ENGIN-X INSTRON: create 32-bit releases

[Tom-Willemsen]

Where?

Modify our release process so that we can create 32-bit EPICS builds alongside the existing 64-bit builds.

The deploy script should be modified to give us an option to deploy 32 or 64-bit builds, defaulting to whichever is currently installed, and with appropriate documentation to help future developers choose an appropriate build.

Note: the build directory and install directory should be c:\instrument\apps\epics, not c:\instrument\apps\epics32.

Acceptance criteria

• Our release process creates 32-bit builds as standard as well as the existing 64-bit
• Deploy script can deploy 32-bit builds as well as the existing 64-bit
