Steps to reproduce (Include if Applicable)

git clone https://github.com/nativium/nativium-modules.git
make build-ios

You can see that inside nativium/build/ios/release/ios/arm64/conan/conanbuildinfo.txt you will have:

I solved the problem.

The flags are not filled because of C support of CMake.

I need enable it changing from:

project(nativium LANGUAGES CXX)

Hi @franramirez688,

I already tried it, but it don’t work with all dependencies.

I open an issue in the past to talk about this: https://github.com/conan-io/conan/issues/12197

Because this o created mine that work with all dependencies.
