Did you try to separate you VAR1 and VAR2 def suing semicolon as indicated
in the doc:
"The COMPILE_DEFINITIONS property may be set to a semicolon-separated
list of preprocessor definitions using the syntax VAR or VAR=value."

see
cmake --help-property COMPILE_DEFINITIONS

so try:
set_source_files_properties(source.cpp
PROPERTIES COMPILE_DEFINITIONS "VAR1=${MY_VAR1};VAR2=${MY_VAR2}" )
