For Android im getting this error:

======== Installing packages ========
ERROR: There are invalid packages:
fmt/9.1.0: Invalid: 'settings.os.api_level' value not defined
spdlog/1.11.0: Invalid: 'settings.os.api_level' value not defined

What i need define to be captured by the conan cmake provider?

Command:

cmake -S . -B /Users/paulo/Developer/workspaces/cpp/xplpc/build/kotlin/armeabi-v7a -DXPLPC_TARGET=kotlin -DXPLPC_ADD_CUSTOM_DATA=ON -DCMAKE_BUILD_TYPE=RelWithDebInfo -DXPLPC_DEPENDENCY_TOOL=conan -DCMAKE_TOOLCHAIN_FILE=/Applications/AndroidNDK.app/Contents/NDK/build/cmake/android.toolchain.cmake -DCMAKE_PROJECT_TOP_LEVEL_INCLUDES=build/conan/conan_provider.cmake

Can you help me here @memsharded?

It not an error with conan, because it build, but cmake can't find the dependencies. Maybe the CMAKE_MODULE_PATH or CMAKE_PREFIX_PATH was not defined to this case.

Hi @paulocoutinhox, Android support is now on develop2 if you want to try it out. You should just be able to use the documented inputs for the Android toolchain to get it to work. If you want specific commands to try out, I recommend starting with the ones in the smoke test.

iOS support is currently under review.

I haven't tried an Emscripten build yet, but I was getting a similar error with the Android toolchain that has since been fixed. More details here. If it's still not working, happy to take a look.
