### Explanation of Changes:
1. **Added `BuildRequires: libiniparser-devel`:**
   - This ensures that the development headers and libraries for `iniparser` are available during the build process.
   - Without this, the compiler cannot find `iniparser.h`, leading to the error observed in the build log.

2. **No changes to other parts of the file:**
   - The rest of the file remains unchanged as it already correctly defines the build and installation steps.

This modification should resolve the build failure by ensuring that the required header files are present during compilation.
