Building plugin installers with CPack productbuild generator

CMake
1

I’m trying to set up CPack for building my plugin installers (with CPack’s productbuild generator, to generate a .pkg package on Mac).

I’m calling the install commands with relative paths in my cmakelists like this:

install (TARGETS MyVST3
         DESTINATION "Library/Audio/Plug-Ins/VST3"
         COMPONENT MyVST3)

install (TARGETS MyAU
         DESTINATION "Library/Audio/Plug-Ins/Components"
         COMPONENT MyAU)

and then after I build the .pkg, it appears to be prepending Applications/ to the payload paths – it displays the destination paths as ./Applications/Library/Audio/Plug-Ins/VST3/ and ./Applications/Library/Audio/Plug-Ins/Components/

Is this just a property of CPack’s productbuild generator, does it automatically prepend Applications/ to all destination paths?

hmm, it seems that if I set CPACK_PACKAGING_INSTALL_PREFIX to "/" in my cmakelists, this prevents Applications/ from being prepended to all the destination paths.
