GGML symbols are not visible

[paulocoutinhox]

Hi,

I have created a simple project to demonstrate it that simply compile ggml and a file (main.cpp) try use it:
https://github.com/paulocoutinhox/ggml-test

But the error is that ggml methods are not visible:
https://github.com/paulocoutinhox/ggml-test/actions/runs/6570636731/job/17848379609#step:6:391

I tried a lof of options and nothing.

There is something that i need set in CMake to make ggml visible? Their symbols are not visible.

Hi,

The solution is add C to project language:

project(xplpc LANGUAGES C CXX)

Thanks.
