That's news for everyone using CMake. A simple CMake test shows:
[100%] Building C object CMakeFiles/test.dir/test.c.o
/usr/bin/gcc -o CMakeFiles/test.dir/test.c.o -c /home/hendrik/tmp/cmake
test/test.c
So RelWithDebInfo is _NOT_ the default setting. The default setting on Linux is
an empty CMAKE_BUILD_TYPE variable.
However, combined with automatically evaluated CPPFLAGS/CFLAGS/CXXFLAGS/...,
the result may be the same.
Also testing in Lintian for the -DCMAKE_BUILD_TYPE=RELEASE is plain wrong, as
it may be configured using other -D settings. Not using -DNDEBUG for CFLAGS is
new to me, though.
