libcamera: fix c++ flags and failed buildpaths QA check
Building libcamera from the latest version of meta-or fails
the buildpaths qa check with a number of generated binaries.
Looking into the logs, it seemed that the -f*-prefix-map
flags were present to gcc invocations, but the used flags
were quite off for g++ invocations. It seems that using
the cpp_args meson option overwrites (at least most of)
the CXXFLAGS set by Yocto, including the -f*-prefix-map
flags.
To avoid this, append the extra compile flag to the
CXXFLAGS variable instead of using meson's cpp_args option.
