There is no CMake target property PRIVATE_INCLUDE_DIRECTORIES, just
INCLUDE_DIRECTORIES (PRIVATE and PUBLIC directories) and
INTERFACE_INCLUDE_DIRECTORIES (PUBLIC and INTERFACE directories).
Building on Linux with -DKICAD_USE_EGL=ON but without a system-wide GLEW
fails without this change.
wxWidgets 3.1.5+ on Linux will compile with the Wayland EGL
canvas as the backend instead of the X11 backend. This requires a
version of GLEW compiled with the proper EGL defines and a different
header/code for certain parts that are X11 GLEW specific.
This introduces an in-tree version of GLEW that will be built with the
GLEW_EGL flag then statically linked into the KiCad executables when
EGL support is needed.
We want to be somewhat standards compliant if we can.
There is a small complication, which we work around:
gcc sets __STRICT_ANSI__ in "c++11" mode (the non-strict mode would be
"gnu++11"), which causes the "strdup" definition to go away. If wx < 3.1 is
compiled with GNU extensions, it just forwards the wxCRT strdup function to
system strdup and doesn't create a definition for the wxCRT function, and
when a program is then compiled in strict mode against that, the wxCRT
function is missing.
From 3.1 onwards, the function is provided unconditionally in wx, so the
workaround is no longer needed there.
This moves the generated files out of the source tree and into
the build directory. They are now regenerated each time they are
needed, based on the timestamp of the generated file compared to
the timestamp of the lemon file.
To do this, we also bundle lemon into the thirdparty directory
and build it for ourselves since it is a very tiny program and
not all platforms seem to distribute it in a consistent manner.

This is required, because Ninja otherwise doesn't properly rebuild after
updating the version string header file.
Because BYPRODUCTS requires CMake 3.2, bump the minimum version and remove
now unused compatibility code for older CMake versions.
It is already added with MSVC, and must be added with gcc/mingw
However, the cmake option:
add_definitions( -DBOOST_UUID_FORCE_AUTO_LINK )
does not work on msys2 (at least with my cmake version), so another syntax is used.
* Split up the thirdparty code into the thirdparty folder (#3637)
* Create a new kimath static library containing all the math functions
This is part of cleaning the build system for #1906.
