Fix spdlog dependency order error

[izzy2lost]

Remove duplicate spdlog declaration to fix Android dependency ordering issues.

The problem was that spdlog was declared twice with conflicting versions (v1.13.0 in the main CMakeLists.txt and v1.14.1 in libultraship/cmake/dependencies/android.cmake), leading to build errors. This change ensures libultraship correctly manages the spdlog dependency for Android builds.

Summary of Changes

Hello @izzy2lost, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

I've addressed a build error related to the spdlog dependency for Android builds. The issue stemmed from spdlog being declared twice with conflicting versions in different CMake files. This change removes the redundant declaration in the main CMakeLists.txt to ensure libultraship correctly manages the spdlog dependency.

Highlights

• Dependency Resolution: I've resolved a build error for Android by removing a duplicate spdlog dependency declaration.
• CMake Refinement: Specifically, I removed the FetchContent block for spdlog (version 1.13.0) from the main CMakeLists.txt file, which was causing conflicts with another declaration (version 1.14.1) in libultraship/cmake/dependencies/android.cmake.
• Include Path Cleanup: As a result of removing the duplicate declaration, I also removed the corresponding spdlog include directory from the global include_directories list in CMakeLists.txt.

Code Review

This pull request correctly removes a duplicate spdlog dependency declaration for Android builds and a related hardcoded include path. This helps resolve build errors caused by conflicting versions. My review includes a comment on a potential remaining versioning issue for spdlog on Android that you might want to look into to ensure the intended version is being used.

[gemini-code-assist]

Removing this duplicate spdlog declaration is the correct approach to fix the build errors on Android.

However, there might be a lingering issue with the spdlog version being used. libultraship/cmake/dependencies/common.cmake declares spdlog v1.13.0, and it's included before libultraship/cmake/dependencies/android.cmake, which declares v1.14.1. Because of the if (NOT ${spdlog_FOUND}) check in android.cmake, the v1.14.1 declaration will be skipped, and Android will end up using v1.13.0 from common.cmake.

If the intention is for Android to use v1.14.1, you might need to adjust the logic in libultraship's CMake files, for example by removing the spdlog handling from common.cmake when building for Android.

Try to build in GitHub actions with android compile

@cursoragent try to build in GitHub actions with the android-compile.yml

I tried to trigger the GitHub Actions workflow for the Android build, but after several attempts using the GitHub CLI (which I had to install and authenticate), I discovered that the access token I was using didn't have the necessary permissions to trigger workflows directly. I was able to list workflows and see their statuses, confirming that recent Android builds had failed.

Since I couldn't trigger the build, I've ensured that the changes I made to fix the spdlog dependency order are committed and pushed. These changes involve:

• Modifying CMakeLists.txt: I added the spdlog declaration for Android before torch and libultraship are included, using version v1.14.1 to match libultraship's version. This ensures spdlog is available when torch tries to find it.
• Updating libultraship/cmake/dependencies/android.cmake: I added target checks to prevent duplicate spdlog declarations and preserved the SDL2 linking for ImGui.

Because I can't trigger the workflow myself, you'll need to manually trigger the "Android Build" workflow from your GitHub repository's "Actions" tab, selecting the cursor/fix-spdlog-dependency-order-error-ba4a branch. Alternatively, you can push a small, empty commit to trigger the workflow. The build should now succeed as spdlog is declared correctly, torch will find it, and libultraship will skip its own declaration, preventing version conflicts.
