Add KICAD_USE_FONT_REDUCED_SET (default OFF) to build options.

It allow using the previous font set without CJK.
The new font (with CJK) is very large (10x), and can create (on Opengl) out of memory issues
with some graphic cards.

+
+KICAD_SCRIPTING_ACTION_MENU
+    Build a tools menu with registered python plugins: actions plugins.

+KICAD_USE_FONT_REDUCED_SET
+    Build KiCad with a reduced font set, without CKJ font.
+    Avoid out of memory issue with some graphic cards on OpenGL.
+    Default OFF.
+
+BUILD_SMALL_DEBUG_FILES
+    In debug build: create smaller binaries.
+
+    On Windows, binaries created by link option -g3 are *very large*
+    (more than 1Gb for pcbnew, and more than 3Gb for the full kicad suite)
+    This option create binaries using link option -g1 that create much smaller files, but
+    there are less info in debug (However the file names and line numbers are available)
+    Default OFF.
+
+# Not supported by all platforms (for instance mingw)
+KICAD_SANITIZE
+    Build KiCad with sanitizer options.
+    WARNING: Not compatible with gold linker.
+    Default OFF.
+
+KICAD_STDLIB_DEBUG
+    Build KiCad with libstdc++ debug flags enabled.
+    Default OFF.
+
+option( KICAD_STDLIB_LIGHT_DEBUG
+    Build KiCad with libstdc++ with -Wp,-D_GLIBCXX_ASSERTIONS flag enabled.
+    Not as intrusive as KICAD_STDLIB_DEBUG
+    Default OFF.
+
+KICAD_BUILD_PARALLEL_CL_MP
+    Build in parallel using the /MP compiler option (Default OFF for safety reasons).
+    Default OFF.
+
+option( KICAD_USE_VALGRIND
+    Build KiCad with valgrind stack tracking enabled.
+    Default OFF.
+
+When option KICAD_SCRIPTING OR KICAD_SCRIPTING_MODULES is enabled:
+  PYTHON_EXECUTABLE can be defined when invoking cmake
+  ( use -DPYTHON_EXECUTABLE=<python path>/python.exe or python2 )
+  when not defined by user, the Default is python.exe under Windows and python2 for others
+  python binary file should be in exec path.
+
+Note 1:
+    KICAD_SCRIPTING controls the entire python scripting system.
+    If it is off, no other scripting is allowed
+
+    Therefore, if KICAD_SCRIPTING is OFF, these other option are forced to OFF:
+        KICAD_SCRIPTING_MODULES, KICAD_SCRIPTING_ACTION_MENU,KICAD_SCRIPTING_PYTHON3
+        KICAD_SCRIPTING_WXPYTHON, KICAD_SCRIPTING_WXPYTHON_PHOENIX
+
+Note 2:
+    KICAD_SCRIPTING_WXPYTHON_PHOENIX requires enabling the KICAD_SCRIPTING_WXPYTHON flag
+    so that the wxWidgets library is properly versioned
+
+
+Note 3
+    These Symbols are always defined, and are not an option for cmake invocation:
+
+
+COMPILING_DLL:
+
+    This is a signal to import_export.h, and when present, toggles the
+    interpretation of the #defines in that file. Its purpose should not be
+    extended beyond this.
+
+
+USE_KIWAY_DLLS:
+
+    Comes from CMake as a user configuration variable, settable in the Cmake
+    user interface. It decides if KiCad will be built with the *.kiface program
+    modules.
+
+
+BUILD_KIWAY_DLL:
+
+    Comes from CMake, but at the 2nd tier, not the top tier. By 2nd tier,
+    something like pcbnew/CMakeLists.txt, not /CMakeLists.txt is meant. It is
+    not a user configuration variable. Instead, the 2nd tier CMakeLists.txt file
+    looks at the top level USE_KIWAY_DLLS and decides how the object files under
+    the 2nd tier's control will be built. If it decides it wants to march in
+    lockstep with USE_KIWAY_DLLS, then this local CMakeLists.txt file may pass a
+    defined BUILD_KIWAY_DLL (singular) on the compiler command line to the
+    pertinent set of compilation steps under its control.
