build chain fix to disable vendors
fixing OPCUA-1421
build chain now supports optional vendor switch off, to avoid dragging along unneeded dependencies and hacking the build chain. Defaults are as before
you will have to switch off vendor builds if you want ONLY mockup, using the toolchain
SET( CANMODULE_BUILD_VENDORS “OFF”) (default is “ON”)
you can switch off selected vendor which you do not need using the toolchain
SET(CANMODULE_BUILD_SYSTEC “OFF”)
SET(CANMODULE_BUILD_ANAGATE “OFF”)
SET(CANMODULE_BUILD_PEAK “OFF”)
(default is all "ON")
