Fix MinGW and MacOS dynamic library build (v2.4 BDAP only)

[AmirAbrams]

Describe the issue

v2.4 (BDAP) branches fail to build using MacOS and MinGW when you use --with-libs in the configure.

Steps to reproduce

1. Using MacOS or MinGW, you get a linker error when building binaries with libraries: ./autogen.sh && ./configure --with-libs && make
