CK Build - Build Composable Kernel targets in Docker

Usage: ck-build [options] [target...]

Options:
  -h, --help              Show this help message
  --name <name>           Specify container name
  --reconfigure           Reconfigure CMake before building
  -j <N>                  Parallel jobs (passed to ninja)
  --clean                 Clean before building

Arguments:
  target                  Target(s) to build (default: all)

Environment:
  CK_CONTAINER_NAME - Override default container name
  GPU_TARGET        - Override GPU target detection (e.g., gfx950, gfx942)

Examples:
  ck-build                                # Build all targets
  ck-build test_amdgcn_mma                # Build specific target
  ck-build test_amdgcn_mma test_gemm      # Build multiple targets
  ck-build --reconfigure                  # Reconfigure CMake and build all
  ck-build --clean test_amdgcn_mma        # Clean and build target
  ck-build -j 8 test_amdgcn_mma           # Build with 8 parallel jobs
