Indeed everything works that way, many thanks, guys.

No, it doesn't double anything.
Without the outside_deps, the executable wouldn't link if it needed
something from them.
With them, it will link, and be as small a size as the linker can make
it. (Assuming a release build, where the linker leaves out what it
doesn't need...)

Subject: Re: [CMake] Sharing sources between two targets
That doubles the size of the executable, because if I do something like
that:
ADD_LIBRARY(temp STATIC ${sources})
TARGET_LINK_LIBRARIES(temp outside_deps)
ADD_EXECUTABLE(code main.cpp)
TARGET_LINK_LIBRARIES(code temp)
then TARGET_LINK_LIBRARIES(...) also add outside_deps as link libraries
for code, so they end up included twice.

Hi Nick,
What about creating a static library that would be linked against both
the executable and the library ?

Folks,
I am using CMake to create 2 targets - a stand-alone executable
and
a library that can be imported by Python. Both share most of the
sources. If I just specify them as two separate targets, each will
compile all the sources, so most of the source files end up
compiled
twice.
Is there a way to share the compiled sources between the two
targets? I can create an intermediate library, but that is less
convenient since the executable will then depend on it. What I
would
really like is to have a self-contained executable and a separate
library that use the same object files.
Many thanks for any hint,
Nick Gnedin
