Missing igraph_version.h in libigraph-dev Package on Ubuntu 24.04

[sanchuanhehe]

### **Bug Report: Missing `igraph_version.h` in `libigraph-dev` Package on Ubuntu 24.04**

#### **1. Affected Package**
- **Package Name**: `libigraph-dev`
- **Ubuntu Version**: Ubuntu 24.04.2 LTS (Noble)
- **Package Version**: `0.10.10+ds-1.1build2` (amd64)

---

#### **2. Issue Description**
After installing the `libigraph-dev` package on Ubuntu 24.04, the header file `igraph_version.h` is missing from the expected directory `/usr/include/igraph/`. This causes compilation errors when trying to use `igraph`, such as:

```c
fatal error: igraph_version.h: No such file or directory
```

---

#### **3. Steps to Reproduce**
1. Install `libigraph-dev`:
   ```sh
   sudo apt update
   sudo apt install libigraph-dev
   ```
2. Check for missing header files:
   ```sh
   ls -l /usr/include/igraph/
   dpkg -L libigraph-dev | grep '\.h$'
   ```
3. `igraph_version.h` is not present in `/usr/include/igraph/`, leading to compilation failures.

---

#### **4. Expected Behavior**
After installing `libigraph-dev`, the following header files should be available in `/usr/include/igraph/`:
```sh
/usr/include/igraph/igraph.h
/usr/include/igraph/igraph_types.h
/usr/include/igraph/igraph_attributes.h
/usr/include/igraph/igraph_version.h # MISSING
```
However, `igraph_version.h` is missing, making it impossible to compile programs that depend on it.

---

#### **5. Possible Solutions**
- Verify the packaging process of `libigraph-dev` to ensure all required headers, including `igraph_version.h`, are correctly included.
- If the issue originates from the upstream Debian package, sync with the latest version or report it to Debian maintainers.
