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

targets I Don't want it defined. Does that make sense?
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).
