Windows Shared Library Missing Exports

[dunkleyr]

I can pull the latest master branch and open in Visual Studio 2022 and it builds the executables and shared libraries fine; however, I would like to use the shared library SZ3c.dll directly instead of calling the executable. The library built and placed at /out/build/x64-Debug/tools/sz3c/SZ3c.dll does not appear to have any exported functions. Is there an easy way to export SZ_compress_args and SZ_decompress functions so they can be called dynamically using SZ3c.dll.

I tried adding the following to CMakeLists.txt file:

set(CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS 1)

But it didn't seem to change anything. I also added the following lines based on some google searches:

include(GenerateExportHeader)
generate_export_header(SZ3c)

The build then generated a sz3c_export.h file, but it doesn't have the functions in it or in the final DLL. I feel like this should be easy, but I am new to CMAKE and can't seem to find a solution online. Anyone know how this could be done?
