Hello,
Wow that was fast. Thanks a lot.
Obviously I was too fast reading the doc :-)
[...]
SET_TARGET_PROPERTIES(PlatformLib PROPERTIES
DEFINE_SYMBOL
USE_TRACER)
Then you shouldn't have to ADD_DEFINITIONS and
REMOVE_DEFINITIONS?
I do not understand why.. but DEFINE_SYMBOL did not work, but
COMPILE_FLAGS -DUSE_TRACER
did. So SET_TARGET_PROPERTIES is the sledgehammer for getting it
done :)
DEFINE_SYMBOL only works for shared libraries. see cmake
documentation: "DEFINE_SYMBOL sets the name of the preprocessor
symbol defined when compiling sources in a shared library."
Thank you Christian
...for reading the doc more carefully than I do :-)

and I _think_ that DEFINE_SYMBOL only will work on windows as it is
there to facilitate the dllImport/dllexport functionality used by
windows for exporting/importing symbols from shared libraries.
I may be wrong on that as I am going on memory at this point.
This is wrong - you've a similar option with gcc - the visibility
attribute.
Christian
Yep. you are correct. I was away from my machine and so was obviously
remembering things in-correctly.
Mike
