[Cmake] SET_TARGET_PROPERTIES + DEFINE_SYMBOL

[ibiris at genius.org.br]

Greetings,

I noticed that when I am trying to use SET_TARGET_PROPERTIES to set the
property DEFINE_SYMBOL on a target that is a library (added with
ADD_LIBRARY), the appropriate precompiler definition (-DXXX) does not
appear in the generated Makefile for the library.

Separately from the CMakeLists.txt for my library I also have a
CMakeLists.txt for an  executable being built linking against the compiled
library. Though the SET_TARGET_PROPERTIES was not added for this executable
target the symbols passed through the DEFINE_SYMBOL properties used on the
library target appear in the Makefiles for the executable.

So what is happening is roughly the following

---
... in CMakeLists.txt for xlib ...

ADD_LIBRARY(xlib SHARED f1.c f2.c)
SET_TARGET_PROPERTIES( xlib       DEFINE_SYMBOL __FOO__
DEFINE_SYMBOL  __BAR__)


... in CMakeLists.txt for aexec ...
ADD_EXECUTABLE( aexec a.c b.c)
TARGET_LINK_LIBRARIES(aexec xlib)
---

the symbols __FOO__ and __BAR__ appear in the Makefile for aexec instead of
the Makefile for xlib ...

Ideas? I am a bit stuck (and yes I have checked that the correct target
names are passed to SET_TARGET_PROPERTIES) ...

Thanks in advance for your kind help :-)
