Add support for OrcaSlicer 2.3.1-alpha infill rotation template warning

Implement a check for projects created with OrcaSlicer 2.3.1-alpha to warn users about potential issues with infill rotation template settings. If the infill pattern is not safe to rotate, prompt the user to clear the rotation template settings to avoid print quality issues.

 ## Development Workflow
 
-### Code Style
-- C++17 standard
-- Use existing patterns found in libslic3r for consistency
-- Follow existing naming conventions (PascalCase for classes, snake_case for functions)
+### Code Style and Standards
+- **C++17 standard** with selective C++20 features
+- **Naming conventions**: PascalCase for classes, snake_case for functions/variables
+- **Header guards**: Use `#pragma once` 
+- **Memory management**: Prefer smart pointers, RAII patterns
+- **Thread safety**: Use TBB for parallelization, be mindful of shared state
 
-### Common Tasks
-- **Adding new print settings**: Extend `PrintConfig.cpp` and related GUI components
-- **Modifying slicing algorithms**: Work in `libslic3r/` core modules
-- **GUI changes**: Modify components in `src/slic3r/GUI/`
-- **Adding printer support**: Add profiles in `resources/profiles/`
+### Common Development Tasks
 
-### Dependencies Management
-Dependencies are managed through CMake and built separately from the main application. The `deps/` directory contains dependency build configurations.
+#### Adding New Print Settings
+1. Define setting in `PrintConfig.cpp` with proper bounds and defaults
+2. Add UI controls in appropriate GUI components  
+3. Update serialization in config save/load
+4. Add tooltips and help text for user guidance
+5. Test with different printer profiles
 
-## Important Notes
+#### Modifying Slicing Algorithms  
+1. Core algorithms live in `libslic3r/` subdirectories
+2. Performance-critical code should be profiled and optimized
+3. Consider multi-threading implications (TBB integration)
+4. Validate changes don't break existing profiles
+5. Add regression tests where appropriate
 
-- The codebase is large and complex - use search tools to navigate effectively
-- Many algorithms are performance-critical - consider computational complexity
-- The project maintains backward compatibility with various file formats
-- Cross-platform compatibility is important (Windows, macOS, Linux)
-- The GUI uses a custom theming system supporting light/dark modes
+#### GUI Development
+1. GUI code resides in `src/slic3r/GUI/` (not visible in current tree)
+2. Use existing wxWidgets patterns and custom controls
+3. Support both light and dark themes
+4. Consider DPI scaling on high-resolution displays
+5. Maintain cross-platform compatibility
+
+#### Adding Printer Support
+1. Create JSON profile in `resources/profiles/[manufacturer].json`
+2. Add printer-specific start/end G-code templates
+3. Configure build volume, capabilities, and material compatibility
+4. Test thoroughly with actual hardware when possible
+5. Follow existing profile structure and naming conventions
+
+### Dependencies and Build System
+- **CMake-based** with separate dependency building phase
+- **Dependencies** built once in `deps/build/`, then linked to main application  
+- **Cross-platform** considerations important for all changes
+- **Resource files** embedded at build time, platform-specific handling
+
+### Performance Considerations
+- **Slicing algorithms** are CPU-intensive, profile before optimizing
+- **Memory usage** can be substantial with complex models
+- **Multi-threading** extensively used via TBB
+- **File I/O** optimized for large 3MF files with embedded textures
+- **Real-time preview** requires efficient mesh processing
+
+## Important Development Notes
+
+### Codebase Navigation
+- Use search tools extensively - codebase has 500k+ lines
+- Key entry points: `src/OrcaSlicer.cpp` for application startup
+- Core slicing: `libslic3r/Print.cpp` orchestrates the slicing pipeline
+- Configuration: `PrintConfig.cpp` defines all print/printer/material settings
+
+### Compatibility and Stability
+- **Backward compatibility** maintained for project files and profiles
+- **Cross-platform** support essential (Windows/macOS/Linux)  
+- **File format** changes require careful version handling
+- **Profile migrations** needed when settings change significantly
+
+### Quality and Testing
+- **Regression testing** important due to algorithm complexity
+- **Performance benchmarks** help catch performance regressions
+- **Memory leak** detection important for long-running GUI application
+- **Cross-platform** testing required before releases

+# CMake Interfaces for deps_src Libraries
+
+This document describes how to use the CMake interface libraries created for the subdirectories in `deps_src/`.
+
+## Available Libraries
+
+### 1. **semver** (Static Library)
+- **Type**: Static library
+- **Target**: `semver` or `semver::semver`
+- **Headers**: `semver.h`
+- **Usage**:
+```cmake
+target_link_libraries(your_target PRIVATE semver)
+# or
+target_link_libraries(your_target PRIVATE semver::semver)
+```
+
+### 2. **hints** (Interface Library)
+- **Type**: Interface library (header-only)
+- **Target**: `hints`
+- **Utility**: `hintsToPot` executable
+- **Usage**:
+```cmake
+target_link_libraries(your_target PRIVATE hints)
+```
+
+### 3. **spline** (Interface Library)
+- **Type**: Interface library (header-only)
+- **Target**: `spline` or `spline::spline`
+- **Headers**: `spline.h`
+- **Usage**:
+```cmake
+target_link_libraries(your_target PRIVATE spline)
+# or
+target_link_libraries(your_target PRIVATE spline::spline)
+```
+
+### 4. **stb_dxt** (Interface Library)
+- **Type**: Interface library (header-only)
+- **Target**: `stb_dxt` or `stb_dxt::stb_dxt`
+- **Headers**: `stb_dxt.h`
+- **Usage**:
+```cmake
+target_link_libraries(your_target PRIVATE stb_dxt)
+# or
+target_link_libraries(your_target PRIVATE stb_dxt::stb_dxt)
+```
+
+## How to Use in Your Project
+
+### From within the OrcaSlicer src/ directory:
+
+1. **In your CMakeLists.txt**, simply link the library:
+```cmake
+add_executable(my_app main.cpp)
+target_link_libraries(my_app 
+    PRIVATE 
+        semver::semver      # For version parsing
+        spline::spline      # For spline interpolation
+        stb_dxt::stb_dxt    # For DXT texture compression
+        hints               # For hints functionality
+)
+```
+
+2. **In your C++ code**, include the headers:
+```cpp
+// For semver
+#include <semver.h>
+
+// For spline
+#include <spline.h>
+
+// For stb_dxt
+#include <stb_dxt.h>
+
+// Use the libraries as documented in their respective headers
+```
+
+## Benefits of This Approach
+
+1. **Modern CMake**: Uses target-based CMake with proper INTERFACE/PUBLIC/PRIVATE visibility
+2. **Proper Include Paths**: Automatically sets up include directories
+3. **Namespace Aliases**: Provides namespaced aliases (e.g., `spline::spline`) for clarity
+4. **Position Independent Code**: Static libraries are built with `-fPIC` for compatibility
+5. **Install Support**: Libraries can be installed and used by external projects
+6. **Build/Install Interface**: Separates build-time and install-time include paths
+
+## Example Integration
+
+Here's a complete example of using these libraries in a new component:
+
+```cmake
+# In src/mycomponent/CMakeLists.txt
+add_library(mycomponent STATIC
+    mycomponent.cpp
+    mycomponent.h
+)
+
+target_link_libraries(mycomponent
+    PUBLIC
+        semver::semver  # Version handling is part of public API
+    PRIVATE
+        spline::spline  # Used internally for interpolation
+        stb_dxt::stb_dxt # Used internally for texture compression
+)
+
+target_include_directories(mycomponent
+    PUBLIC
+        $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}>
+        $<INSTALL_INTERFACE:include>
+)
+```
+
+## Notes
+
+- All header-only libraries use the INTERFACE library type, which means they don't produce any binaries
+- The `semver` library produces a static library that will be linked into your target
+- The `hints` project also produces a `hintsToPot` executable utility
+- All libraries require at least C++11 (some require C++17)
