[CMake] Adding definitions to compile one file ?

[Petr Kmoch]

Hi Vania.

For your case, it's best to forget about the
not-as-convenient-as-they-could-be convenience functions set_*_properties,
and just invoke set_property:

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