Compiling on MacOS: Undefined symbols for architecture arm64: "dummy_register()"

[jeffrafter]

I might be doing something wrong but when following the instructions in the README I encountered the following on MacOS:

❯ cmake --build build --config Release                                                                             (base) 
[ 13%] Built target ggml-base
[ 20%] Built target ggml-metal
[ 31%] Built target ggml-cpu
[ 34%] Built target ggml-blas
[ 39%] Built target ggml
[ 74%] Built target tts
[ 75%] Linking CXX executable ../../bin/tts-cli
ld: warning: ignoring duplicate libraries: '../../ggml/src/libggml.a'
Undefined symbols for architecture arm64:
  "dummy_register()", referenced from:
      __GLOBAL__sub_I_loaders.cpp in libtts.a[10](loaders.cpp.o)
ld: symbol(s) not found for architecture arm64
c++: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [bin/tts-cli] Error 1
make[1]: *** [examples/cli/CMakeFiles/tts-cli.dir/all] Error 2
make: *** [all] Error 2

In order to get around this I changed src/models/CMakeLists.txt from:

target_sources(tts PRIVATE
        loaders.cpp
        loaders.h
)

add_subdirectory(dia)
if (LINUX)
    add_subdirectory(dummy)
endif ()
add_subdirectory(kokoro)
add_subdirectory(orpheus)
add_subdirectory(parler)

to:

target_sources(tts PRIVATE
        loaders.cpp
        loaders.h
)

add_subdirectory(dia)
add_subdirectory(dummy)
add_subdirectory(kokoro)
add_subdirectory(orpheus)
add_subdirectory(parler)

After that everything compiles and works. I'm wondering why this was limited only to Linux but my guess is that it has to do with espeak (which I am not using). Happy to submit a PR if this solution is okay.

Seems like this is a problem introduced by 37baf31. However, it should be fixed in #117 the PR also removes the condition check.
