[gdal-dev] Building GDAL on Ubuntu 22.04

[Even Rouault]

I definitely ran into build issues in that past related to missing 
libstdc++ (perhaps related to using older CMake and/or clang?). But 
looking closer, we only add -lstdc++ when building a test program fails 
without this explicit addition. Cf 
https://github.com/OSGeo/gdal/blob/master/cmake/helpers/GdalCompilationFlags.cmake#L165 
to L183
