Solution: we can use 'CMAKE_SYSTEM_VERSION' instead of
'${CMAKE_SYSTEM_VERSION}' for the 'if' clauses.
CMake fails to evaluate condition when CMAKE_SYSTEM_VERSION is
empty, which can happen with a default installation of Mingw-w64
in Linux.
Some #define switches cause the body of entire files to be omitted. This
causes a linker warning on Visual Studio 2017, for example
warning LNK4221: This object file does not define any previously
undefined public symbols, so it will not be used by any link
operation that consumes this library
Since this is warning us about something that shouldn't be
earth-shattering news, we add a linker flag to suppress this warning on
MSVC builds.
Add two new options to CMakeLists.txt:
`BUILD_SHARED` - Whether or not to build the shared object (Default: ON)
`BUILD_STATIC` - Whether or not to build the static archive (Default: ON)
Remove the `build/msvc` include path from the test project to fix a
problem with the order of the include paths. Additionally remove the
unnecessary `include_directories` from the master project.

Solution: use pthread API to set the name. For now call every thread
"ZMQ b/g thread". Would be nice to number the I/O threads and name
explicitly the reaper thread, but in reality a bit of internal API
churn would be necessary, so perhaps it's not worth it.
This is useful when debugging a process with many threads.
Solution: set SOVERSION in CMakeLists to match the SONAME generated
by libtool so that there is no mismatch between the output of the
*NIX build systems.

Solution: use only Libs.private to avoid breaking application builds.
Even though Requires.private are supposed to be parsed only if
pkg-config is called with --static, the --cflags parameter is enough
to trigger the parsing, causing build failures for applications that
do not (and should not) depend on libzmq's dependencies.
Solution: add dependencies, if necessary, to the .private Libs and
Requires field of the pkgconfig file at build time.
This way pkg-config --static --libs libzmq will correctly print
dependencies if they were used to build the static libzmq.a library.
Solution:
Add CMake option called WITH_MILITANT so that it aligns with the Autotools
build infrastructure; enabling this option defines ZMQ_ACT_MILITANT, which
enables assertions should malformed requests make their way into
zmq_setsockopt(3) or zmq_getsockopt(3).
Solution: add macro in ZMQSourceRunChecks.cmake and optionally
include the TIPC sources if the support is available.
More importantly, only run the TIPC tests if the support is there.
Solution: Add precompiled flags to CMakeList.txt for faster compiles
+ bonus - removed compilation warning on Windows by adding
add_definitions (-D_WINSOCK_DEPRECATED_NO_WARNINGS)
