[CMake] Syntax of set_target_properties

[Timo Rumland]

Hallo,

I can't figure out what's wrong with my set_target_properties syntax.
My target is "test" and I want to add two compiler options (defines),
-DTEST and -DDIR="./".

I tried the following:

set_target_properties( test PROPERTIES
                       COMPILE_FLAGS -DTEST
                       COMPILE_FLAGS -DDIR="./" )

But then only -DDIR="./" is added to my VS project.

Any idea why?
                       
Thanks a lot
