# Rule: Build uLib with Micromamba

This rule provides instructions for building the uLib project using the micromamba environment.

## Context
- **Environment**: micromamba `uLib`
- **Output Directory**: `build`
- **CPU Usage**: All available cores

## Instructions

1. **Environment Setup**:
   Ensure micromamba is properly initialized and the `uLib` environment is active.
   ```bash
   export MAMBA_EXE="/home/share/micromamba/bin/micromamba"
   export MAMBA_ROOT_PREFIX="/home/share/micromamba"
   export PRESET="clang-make"
   eval "$(${MAMBA_EXE} shell hook --shell bash)"
   micromamba activate uLib
   ```

2. **Full Rebuild (if needed)**:
   If the `build` directory does not exist or a full reconfiguration is required:
   ```bash
   conan install . --output-folder=build/${PRESET} --build=missing --profile=fast
   cmake --preset ${PRESET}
   cmake --build build/${PRESET} -j$(nproc)
   ```

3. **Incremental Build**:
   Run the build command from the root directory, pointing to the `build` folder and using all cores.
   ```bash
   cmake --build build/${PRESET} -j$(nproc)
   ```

4. **Specific Target Build - gcompose**:
   To build a specific target (e.g., gcompose):
   ```bash
   cmake --build build/${PRESET} --target gcompose -j$(nproc)
   ```
