The CMake build produced libthreadx.a and nothing else, so trying ThreadX on
Linux meant using the Makefile beside the port instead. Build the demo the
Makefile builds, for the linux port and its SMP counterpart.
The target is behind an option that defaults off, so an ordinary build is
unchanged and still produces just the library. -DTHREADX_SAMPLE=ON adds it:
cmake -S . -B build -DTHREADX_ARCH=linux -DTHREADX_TOOLCHAIN=gnu \
-DTHREADX_SAMPLE=ON
cmake --build build --target sample_threadx
The include path uses TX_COMMON_DIR rather than naming common or common_smp,
since the top level already resolves which of the two applies.
Verified by building and running both variants. Non-SMP prints
**** ThreadX Linux Demonstration **** (c) 1996-2020 Microsoft Corporation
and SMP prints the SMP banner, both with the demo's thread counters advancing. A
default configure with no THREADX_SAMPLE has no sample_threadx target and still
produces libthreadx.a, so nothing existing moves.
Derived from the two example_build files in #404 by Yanfeng Liu, which had the
same goal. That change also rewrote the top level's SMP selection, added
common_smp/CMakeLists.txt and added ports_smp/linux/gnu/CMakeLists.txt; all three
have since arrived on dev by other routes, so only the sample targets were still
missing. The include path needed adjusting because the original depended on
THREADX_SMP being a string suffix, which it no longer is.

The project guidelines ask for CMake and Ninja, but only 15 of the 59 gnu port
directories had a CMakeLists.txt. None of the 27 AArch64 ports had one, so the
architecture whose examples were repaired over the last few changes still could
not be built the way the project says to build it, and nothing in CI could
compile it.
Add a CMakeLists.txt to the 44 that lacked one. Three of them are templates in
ports_arch, because 34 of the 44 are generated: the ARMv7-A and AArch64 source
lists are uniform within each family, so one template per family serves every
core in it and update.sh distributes it. The other 10 ports have no generator
and get their own file.
Add the toolchain files those ports select, following the shape of
cmake/cortex_a9.cmake. AArch64 needs a base file of its own rather than a
variant of arm-none-eabi.cmake: it has no -marm or -mthumb to choose between and
no -mfloat-abi, and aarch64-none-elf-gcc rejects -mlong-calls outright, so that
flag cannot be carried across. The tools are named without a path, unlike
cmake/cortex_r52.cmake which pins one, because pinning 30 files to a single
machine's directory layout is the problem the previous change removed from the
launch configurations.
Three toolchain files cover ports that already had a CMakeLists.txt but no way
to select it: the Armv8-M mainline gnu ports, cortex_m33, cortex_m55 and
cortex_m85. Without cmake/<arch>.cmake the documented invocation cannot reach
them.
The top level needed one fix. It derives the SMP port directory as
<arch>_smp, but ports_smp/linux and ports_smp/win64 predate that convention and
carry no suffix, so those two could never be configured. Fall back to the bare
name when the suffixed directory is absent. The check only fires when the
suffixed directory does not exist, so no port that already resolved changes
behaviour, and ports_smp/win64's existing CMakeLists.txt becomes reachable too.
Verified by configuring and building every one: 53 of 53 static libraries build
with cmake -G Ninja, using Arm GNU Toolchain 14.3.Rel1 for both arm-none-eabi
and aarch64-none-elf. That covers the 44 new ports plus the 9 that already
worked, and includes ports_smp/linux, which failed before the fallback.
scripts/check_ports.sh passes, so the three templates and their 34 generated
copies agree.
Six gnu ports are still outside the CMake build, all for want of a compiler
rather than a CMakeLists.txt: rxv1, rxv2 and rxv3 need the Renesas RX GNU
toolchain and mips32_interaptiv_smp needs a MIPS one, neither of which is
available here, so writing toolchain files for them would mean shipping
untested guesses. risc-v32 and risc-v64 already build through their own
differently named toolchain files.
