The reason for the bug is that :
- we use system checks in cmake/os/mysql_release.cmake
- we include cmake/os/mysql_release.cmake using CMAKE_USER_MAKE_RULES_OVERRIDE
- this (having system checks based on TRY_COMPILE inside file pointed by
CMAKE_USER_MAKE_RULES_OVERRIDE does not work with cmake 2.8.3,
and according to Kitware was never meant to work, it just happened to work by accident
until 2.8.2 release (though, it seems not to work wiith 2.6.0 either)
Related CMake bug discussing the situation:
http://public.kitware.com/Bug/view.php?id=11469
The fix is to use INCLUDE instead of CMAKE_USER_MAKE_RULES_OVERRIDE as suggested
by Kitware. The downside is that compile flags are not in cache, but this is pure cosmetics.
The functionality is the same, flags are used for compiling are correct using INCLUDE.
Due to the extent of aliasing violations in the MySQL source
code, at this time it is safer to disable strict aliasing related
optimizations in release builds.
As of this patch, only GCC enables strict aliasing by default.
Hence, use the -fno-strict-aliasing option to disable the
aliasing rules.

the way cmake parses, in particular CMAKE_SIZEOF_VOID_P was
uninitialized during the first parse, and the bad values were
cached.
Pull in SIZEOF_VOIDP macro from package_name.cmake, define some
useful variables, and clean up the file a bit with explicit
definitions, to hopefully avoid this problem in the future.

- Corrected spelling ENABLE_LOCAL_INFILE => ENABLED_LOCAL_INFILE
- In addition to "RelWithDebInfo", set target "Release" and "Debug"
- Set Debug flags
- Enabled SSL on Mac OS X
- For gcc builds, set RELEASE and DEBUG flags as well
- For g++ builds, added "-fno-implicit-templates"
- Use "-O" (gcc -O1) for optimized binaries, as "DEBUG" in out case
is more about enabling trace support to the server, no optimization
makes binaries too slow to be practical to reproduce problems
cmake/os/WindowsCache.cmake
- Removed unused HAVE_SYS_IOCTL
config.h.cmake
- Added header checks and missing defines
- Removed unused HAVE_SYS_IOCTL

defines, but internal variables used in the CMake setup,
- Added hard coded flags for HP-UX and Mac OS X
configure.cmake
- Added header checks and missing defines
- Removed unused HAVE_SYS_IOCTL
- "sys/dir.h" test needs "sys/types.h"
- Corrected syntax for "sys/ptem.h" test
- Don't exclude test for some types if Mac OS X, harmless
to do the test and we want the HAVE_<type> settings
