I'm updating a program which previously got compiled with VC2005 (I'm compiling it now with VC2019). One of the source modules was fine with VS2005 but it gives me this compiler error with VS2019:-

Code:
fatal error C1128: number of sections exceeded object file format limit: compile with /bigobj
I'm also converting from a 32-bit build to 64-bit - so maybe that's the problem. Either way... how/where do I set /bigobj ? I've look in the Compiler Properties pages but I can't see anything obvious
