Try to delimit the two definitions by a ; to create a list.

Alternatively set property should do the trick:
https://cmake.org/cmake/help/v3.2/command/set_property.html

set_property(SOURCE source.cpp PROPERTY COMPILE_DEFINITIONS 
VAR1=${MY_VAR1} VAR2=${MY_VAR2})

With set_property you also have the option to specify APPEND or 
APPEND_STRING.

Thanks,
