   Severity: minor   
      
   The debian/rules file specifies the following option to CMake:   
      
       -DCMAKE_BUILD_TYPE="RelWithDebInfo"   
      
   This causes CMake to use its "release with debug info" set of compiler   
   flags. However, the build flags normally used in Debian builds come from   
   dpkg-buildflags(1), and this responds to settings like "noopt" in the   
   DEB_BUILD_OPTIONS environment variable.   
      
   If I try to build the package that way (which I needed to do to debug a   
   segfault in the test suite), I see compile lines like   
      
       $ DEB_BUILD_OPTIONS=noopt dpkg-buildpackage -b   
       [...]

   /SimGearCore.dir/bucket/newbucket.cxx.o -c /tmp/simgear-2024.1.4   
   dfsg/simgear/bucket/newbucket.cxx   
      
   Notice how both -O0 (from dpkg-buildflags) and -O3 (from CMake) are   
   being passed to the compiler.   
      
   My suggested fix is to use   
      
       -DCMAKE_BUILD_TYPE="None"   
      
   which will cause CMake to use only the flags passed in through the   
   standard environment variables, and add none of its own.   
      
   P.S.: The same issue appears in flightgear 1:2024.1.4+dfsg-2.
