As you did not pass --enable-monolithic to configure, you should have
separate plugin files in ipsec/plugins. These are named
libstrongswan-<plugin>.so. They should definitely get installed during
"make install", make sure to copy them to your target.

If you don't have any *.so files, you should check your toolchain if it
properly generates dynamically linked libraries.
