This would erase the previous value of the property COMPILE_DEFINITIONS
specified on the source file(s), if you've already provided one for it. But
the globally specified compilation definitions, flags etc. do not get
copied into these per-source properties. Instead, the final command line
used for compiling a source is combined from the global, target, and source
file properties (and relevant variables and other things).
If you really need to append to the property, though, you can use APPEND or
APPEND_STRING arguments before the PROPERTY keyword; refer to CMake docs
for more details.
