The commit also attempts to avoid the shell command for Windows machines.
If no one has patches to offer for the outstanding CMake bugs, then this is the version that will be moved to the Wiki Patch Page. The community will have to tend to the outstanding bugs when someone with domain experience can work them
This reverts commit 64def346cd. It broke AppVeyor and Travis builds (it tested good locally on Intel, Aarch and Solaris i86). CMake is so fucked up. I regret the day we added it to the project.
We don't know if this is going to fix the issue because we don't have a MinGW platofrm for testing. However, from VRE's answer on Stack Overflow (and the chronic CMake problems with execute_process), we believe this may be the fix.
The fix tested OK on WIndows, Linux, OS X and Cygwin. At worse, it won't do any harm
They are giving ARIA and BLAKE2 trouble. It looks like SSE4 support appeared in the GCC compiler around 4.1 or 4.2. It looks like SHA support appeared in the GNU assembler around 2.18
regtest.cpp is where ciphers register by name. The library has added a number of ciphers over the last couple of years and the source file has experienced bloat. Most of the ARM and MIPS test borads were suffering Out of Memory (OOM) kills as the compiler processed the source fille and the included header files.
This won't stop the OOM kills, but it will help the situation. An early BeagleBoard with 512 MB of RAM is still going to have trouble, but it can be worked around by building with 1 make job as opposed to 2 or 4.
This check-in also enables the 64-bit RDRAND routines for X32. The changes were with held until they could be tested. The testing occurred with Issue 395
Port rdrand.S to Cygwin and OS X
Add DISABLE_NATIVE_ARCH to CmakefileList and GNUmakefile. It supresses the addition of -march=native. DISABLE_NATIVE_ARCH replaces DISABLE_CXXFLAGS_OPTIMIZATIONS in CmakefileList (the latter is now deprecated).
Targets with only object inputs do not work correctly with some
generators (like Xcode, see issue #355). Defining these directly in
terms of the source code files (rather than a reused set of object
files) allows correct builds in such cases. This can now be controlled
through a new option USE_INTERMEDIATE_OBJECTS_TARGET which defaults to
ON.
handy when packaging should control optimization without build system
masking. Especially handy when building to common architecture.
no change of behavior if DISABLE_CXXFLAGS_OPTIMIZATIONS is unset.

Add CRYPTOPP_CROSS_COMPILE variable. Guard host uname calls on CROSS_COMPILE. Set CMAKE_CXX_LINK_FLAGS to CMAKE_CXX_FLAGS. Change to SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} <option>") pattern.
