Statically building pix2pix

[fork-while-1]

Hi!
I want to be able to run pix2pix in SGX, but SGX only supports statically linked programs. So I was wondering if you think it would be possible to build pix2pix statically? I would need the *.a files instead of the *.so files for each of the dependencies, but where do I make the changes in the cmake files for this? Thank you so much for your help!

It may be possible.

In my environment, I was able to find dynamic libraries corresponding to the execution file by running the following command:

pytorch_cpp/static_library/Image-to-Image_Translation/pix2pix$ ldd pix2pix

The following is an example of replacing /lib/x86_64-linux-gnu/libboost_program_options.so.1.71.0 of libboost_program_options.so.1.71.0 => /lib/x86_64-linux-gnu/libboost_program_options.so.1.71.0 (0x00007fd4904dc000) with a static library.

$ ls /lib/x86_64-linux-gnu/libboost_program_options.*

/lib/x86_64-linux-gnu/libboost_program_options.a
/lib/x86_64-linux-gnu/libboost_program_options.so
/lib/x86_64-linux-gnu/libboost_program_options.so.1.71.0

In this case, .a is a static library.
Therefore, I added the following command to the utils/CMakeLists.txt.

This requires adding text for each dynamic library, and it's a little troublesome, but I'm sure it can be done.
