Turns out the CMake guys have already put some of the plumbing into
CMake that I needed. For those playing along at home, I had the rude
awakening to Windows DLL Export fun. So I was looking at other
projects to see how they were doing things. When I built shared
libraries I noticed that CMake was adding a "-DMXADataModel_EXPORTS"
for me, just for the shared library target. Thanks guys. That
simplified my code and CMakeLists.txt a bunch.. Almost like someone
had gone through this before ;-)
Thanks

I have a CMakeLists.txt file with multiple targets in it. A single

psuedo cmake file:
ADD_DEFINITION("_DLLEXPORT") //but I only want this to be applied
to the library?
ADD_LIBRARY(BaseLib ${Base_Sources} )
ADD_DEFINITION("_DLLIMPORT") //and this only for the executable?
ADD_EXECUTABLE(BaseTest ${Base_Test_sources} )
TARGET_LINK_LIBRARIES(BaseTest BaseLib)
How would I do this? Use Target_Properties? Which I know little
about..
That seems to be the answer. I do this:
SET_SOURCE_FILES_PROPERTIES(foo.c PROPERTIES COMPILE_FLAGS -Wno-all)
...which isn't what you want, but based on that, I think you want:
SET_TARGET_PROPERTIES(BaseText PROPERTIES COMPILE_FLAGS -D_DLLIMPORT)
Also note that 'ADD_DEFINITION("_DLLEXPORT")' is wrong, it should
start with '-D' (also you don't need the quotes; I think those are
only needed if you want to pass a string with spaces as a single
argument).
