ninja: build stopped: subcommand failed.

Start with the reported ninja -C build install failure and inspect src/ipa/rkisp1/algorithms/gsl.cpp and src/ipa/rkisp1/algorithms/lsc.cpp, where the compiler errors occur. Reproduce the build on the Raspberry Pi environment described in the issue; done means the libcamera build completes and installation succeeds.
