[CMake] Win32: exporting symbols for DLLs - simpler method ?

[Stephen Collyer]

Cmake seems to define, for each library that is built, a symbol
of the form <library>_EXPORTS, which can be used to set up
#defines for the __declspec(dllexport/dllimport) stuff that
Windows needs.

However, this means that each library needs a specific symbol
to allow it to be built with the correct import/export spec e.g.


class LIB1_EXPORTS Lib1 {
...
}

class LIB2_EXPORTS Lib2 {
...
}

and so on. What I'd like to do is to have a single #define
(LIB_EXPORTS or something) that is set appropriately somehow.

Is this possible ? I don't see how at the moment, but the
method I'm using at the moment is rather tedious and I'd like
to simplify it, if possible.
