I'll help you convert this Bash installation script to use CMake instead of the traditional autotools build system. This will involve creating a CMakeLists.txt file that handles the same functionality.

I've converted the Bash script to a CMake build system. Here's what the CMake version provides:

## Key Features

**Dependency Detection**: Automatically finds required packages using `pkg-config` and CMake's find modules for:
- GLib 2.x, zlib, libusb 1.0, GTK+ 2.x, libglade, libarchive
- Build tools like bison, flex, groff, makeinfo

**Platform-Specific Handling**:
- macOS: Sets install prefix to `/usr/local` and configures PKG_CONFIG_PATH
- Linux 64-bit: Automatically detects if `lib64` should be used

**Build Options**:
- `USE_EXPERIMENTAL`: Use experimental Git branches
- `ENABLE_LOGGING`: Enable logging in libticables  
- `ENABLE_LIBUSB10`: Enable libusb 1.0 support
- `ENABLE_ICONV`: Enable iconv support
- `DISABLE_NLS`: Disable native language support

## Usage

Create a `build` directory and run:

```bash
mkdir build && cd build

# Basic build
cmake ..
make build_all

# With options
cmake -DUSE_EXPERIMENTAL=ON -DCMAKE_INSTALL_PREFIX=/usr/local ..
make build_all
```

## Key Differences from Original Script

1. **Hybrid Approach**: Since the original projects use autotools, this CMake script downloads the Git repositories and still uses their autotools build system via `ExternalProject_Add`
2. **Better Dependency Management**: CMake automatically handles build order and dependencies
3. **Cross-Platform**: Works consistently across Linux, macOS, and other platforms
4. **Configuration Summary**: Shows all settings before building
5. **Options**: Easy to configure build options via `-D` flags

The script maintains all the functionality of the original Bash script while providing a more modern, cross-platform build system approach.
