Use Ninja build system for GDAL compilation

Changed GDAL build from Make to Ninja for faster parallel compilation:
- Added -GNinja to cmake to generate Ninja build files
- Use 'ninja' instead of 'make -j$(nproc)'
- Use 'ninja install' instead of 'make install'

Ninja is faster and more efficient for parallel builds.
ninja-build package is already installed in dependencies.
