What that means?

Hatari CMakefiles.txt sets the default build type to "Release" when
nothing else is specified:
----------
if(NOT CMAKE_BUILD_TYPE)
        set(CMAKE_BUILD_TYPE Release)
endif(NOT CMAKE_BUILD_TYPE)
----------

Hm. It appears I wasn't quite up to date on what Hatari CMake files
do for different build types (IMHO CMake is pretty confusing in that
respect).

CMakeCache.txt tells:
------------------------
//Flags used by the compiler during debug builds.
CMAKE_C_FLAGS_DEBUG:STRING=-g

//Flags used by the compiler during release minsize builds.
CMAKE_C_FLAGS_MINSIZEREL:STRING=-Os -DNDEBUG

//Flags used by the compiler during release builds (/MD /Ob1 /Oi
// /Ot /Oy /Gs will produce slightly less optimized but smaller
// files).
CMAKE_C_FLAGS_RELEASE:STRING=-O3 -g

//Flags used by the compiler during Release with Debug Info builds.
CMAKE_C_FLAGS_RELWITHDEBINFO:STRING=-O3 -g
------------------------

And we have in CMakeFiles.txt:
------------------------
# Building Hatari w/o optimization is no fun...
IF (CMAKE_BUILD_TYPE STREQUAL "Debug")
        set(CMAKE_C_FLAGS "-O ${CMAKE_C_FLAGS}")
ENDIF (CMAKE_BUILD_TYPE STREQUAL "Debug")
-------------------------

I.e. plain "Debug" option builds with "-O" instead of "-O3" and
everything else except MINSIZEREL build type adds debug symbols.

I didn't find where & when stripping is done.

Thomas?
