Fix build with shared libraries

Flakebi · Flakebi · commit 92d067703ac8 · 2025-07-16T14:50:15.000+02:00
With `-DBUILD_SHARED_LIBS=ON`, the command line option gets defined
twice because the source file is included twice, once as part of the
library, once directly in the binary.

Fix this by adding source files only to the library, not to the binary.
