[CMake] Exporting functions from DLLs using standard calling conventions

[Ben Larson]

Hello,

I'm using CMake to manage the build process for a DLL I've created 
mostly from ITK. I have successfully accessed the DLL with a C++ app but 
now want to export the functions using standard calling conventions so I 
can call the DLL from a Visual Basic app. I've got __stdcall in front of 
all of my functions but Visual Studio 6 doesn't seem to be exporting 
them correctly. Configuring a project entirely within VS 6 exports fine 
with __stdcall but the projects with CMake are not. I'm sure I'm missing 
something here. I'm wondering if there are some settings I need to set 
in the CMakeLists.txt file to make sure I'm creating DLLs that are 
exporting functions with standard calling conventions.

Any help would be appreciated,
Ben
