in python's distutils.ccompiler, linker_exe is composed using CC instead
of LDFLAGS. the latter only effects how it builds (shared) library.
and put CMAKE_C_FLAGS into the cflags for the compiler for building
python C extensions, it's more consistent this way. more importantly,
if we build with ASan enabled, the canary program, a.k.a. rados_dummy.c,
won't link without proper CFLAGS.
without this change, rados.so fails to build with errors like:
/usr/bin/ld: /var/ssd/ceph/build/lib/librados.so: undefined reference to
`__asan_stack_free_10'
/usr/bin/ld: /var/ssd/ceph/build/lib/librados.so: undefined reference to
`__asan_report_exp_store8'
...

clang: error: linker command failed with exit code 1 (use -v to see

When building with ccache, distcc, and other compiler wrappers (such
as STLFilt):
CC='ccache gcc' CXX='ccache g++' cmake /path/to/ceph
make
python modules fail to compile since distutils try to execute the
wrapper itself without specifying the actual compiler.
Although cmake has a special magic switch for compiling with ccache
(cmake -DWITH_CCACHE=ON) other tools (distcc) are not supported, and
specifying the compiler as
CC=/whatever/compiler/is
used to work for decades, and it's a good idea to keep it working

we are using GCC7 and up for C++17 support since mimic, and per
https://gcc.gnu.org/onlinedocs/gcc-4.9.1/gcc/AArch64-Options.html ,
GCC 4.9 and up should be able to support crc and crypto features if
these archs are enabled at GCC's configure-time. so we should always use
the -march for detecting the compiler's support instead of using the
inline assembly now.
GCC 4.8 is an ancient compiler, and per
https://gcc.gnu.org/gcc-4.8/changes.html, it was the the first GCC
release which offers AArch64 support. so we don't need to cater for
this GCC version. and we can trust GCC-7 and up.

* add Findcryptopp.cmake back
cryptopp support was dropped in #20015, but it's required by
src/msg/async/dpdk/TCP.h, which `#include <cryptopp/md5.h>`
so, to fix the FTBFS of WITH_DPDK=ON, we need to bring
Findcryptopp.cmake back. it was also removed in #20015.
* pass "-march=core2" when building sources which include dpdk headers.
i was wrong that the headers shipped by distro are generic.
the headers use the sse instructions for speedup memcpy, see
/usr/include/x86_64-linux-gnu/dpdk/rte_memcpy.h .

* add GMock::{GMock,Main}, GTest::{GTest,Main} targets to be

expose the built libraries with properties adhered to
them. so the consumer of them can import them in a better way.

* add dpdk::dpdk if dpdk is built or found, as seastar checks for
it before adding its component libraries. if user installs libdpdk
and builds WITH_SEASTAR=ON or WITH_DPDK=ON, cmake fails to configure
the building system without this fix.
* add dpdk::cflags target for populating the -march=<arch> compile
option.
* also use pkg-config for finding dpdk.
* link common_async_dpdk against dpdk::dpdk instead
please note, the reason why we can remove the "-march=native" compile
option from Finddpdk.cmake, is that the distro shipped header files
are "generic" in the sense of "-march=<ARCH>", they do not enable
the arch specific intrinsic by default, hence the source files
including them do not need specific compiler options.

-march=native causes gcc to use opcodes according to whichever CPU happens to
be installed in the build host, which can be different for every build. This
makes it impossible to achieve a reproducible build.
Also, if the build host has a very new CPU, running the resulting binaries on
older CPUs (of the same family, i.e. x86_64) could result in segmentation
fault.

FindBoost.cmake from upstream cmake now finds python libraries like
find_package(Boost 1.67 python36)
and it export targets like Boost::python36
but we are still linking against Boost::python, so to be compatible
with FindBoost.cmake, we need to update BuildBoost.cmake and
mgr/CMakeLists.txt accordingly. in other words, to export
Boost::python36 and to link Boost::python36.

FMT_VERSION is now living in fmt/core.h in libfmt >= 5.0, so we cannot
parse fmt/format.h for libfmt's version anymore. also we don't need
Findfmt.cmake now. because libfmt-dev 4.0 and up is required by seastar,
also it's libfmt-dev 3.x's cmake module which fails to offer fmt::fmt
target. in other words, it's safe to drop libfmt 3.x support. but 5.0.0
is not compatible with seastar, we will have failures like:

suggested to use the "-fsanitize=${sanitizer}".
please note, this module is compatible with the one used in seastar on
purpose, as seastar is included in ceph using add_subdirectory(), and it
in turn add its own cmake modules directory using list(APPEND ...), so

before this change, we fails to detect std::filesystem with clang++,
because the cmake project created by try_compile() only expands
following options passed from its caller:
- COMPILE_DEFINITIONS
- INCLUDE_DIRECTORIES
- LINK_DIRECTORIES
- LINK_LIBRARIES
which do not include CMAKE_CXX_FLAGS, so either we need to (ab)use
COMPILE_DEFINITIONS for passing -std=c++17, or we can change the
CMAKE_CXX_FLAGS in the parent env, as it turns out the created cmake
project does inherit this flag from current project. in this change,
we use the COMPILE_DEFINITIONS approach: simpler this way. and we
can drop it once cmake 3.8 is required.

we could create a mini project to build a shared library, and use
try_compile() to test if the found gperftools is compiled with -fPIC.
but as we are targeting mostly xenial when enabling
WITH_STATIC_LIBSTDCXX, and google-perftools on xenial by default
is built without -fPIC. so let's keep it simple.
