build, it throws the time stamps away when there are edits to the CMakeLists.txt portion
pertaining to the external project.  Only a 'make clean' would remove the untarred tree.
This patch removes the need to do a make clean when changing the ExternalProject_Add()
text pertinent to patching.

Fixes bug 1250222 in KiCad-Winbuilder

https://svn.boost.org/trac/boost/ticket/8973
https://svn.boost.org/trac/boost/changeset/84950#file0

This is so builders with multiple out of source build trees can all use
the same common boost install directory.  And the build system will not
vascillate between the fuller and lesser subsets of boost.

* Build OpenSSL from source using the OpenSSL-CMake project on Windows with MinGW when no specifying OPENSSL_ROOT_DIR

Add support for building *.deb file using CPack, install ~/fp-lib-table either from kicad-install.sh or from make install_user_configuration_files

Temporarily disable Boost.Context library build as it breaks MinGW builds by bringing in a dependency on MASM (The Microsoft Assembler)

template<> -> template <>
Some more reformatting according to uncrustify results.

*) Set environment variable KISYSMOD before loading FP_LIB_TABLE so that
   FP_LIB_TABLE::ROW::SetFullURI() can do substitution up front.
*) De-emphasize the lib path in some of the footprint frames but keep it
   so the footprint editor can export a current library to another.
   You can even export a GITHUB library to a pretty library for local 
   installation.
*) Start the PLUGIN options editor.
*) Enhance cursor positioning in DIALOG_FP_LIB_TABLE.

* Add save table and set project path environment variable code to
  FP_LIB_TABLE object.
* Add code to Pcbnew and CvPcb to set project path environment variable.
* Create empty footprint table in Pcbnew when new board created.
* Save current project specific footprint library table to path on file save
  as or empty project path.
* Fix a bug in Pcbnew in file save function that would silently overwrite
  an existing board file.
* Disable selecting the current library in the module editor when there are
  no libraries defined.
* Catch exceptions and report errors when writing footprint library tables.
* Fix Boost build CMakeFile to fix bug when bootstrapping a Boost build in
  MSys.

Remove wxUSE_UNICODE definition from CMakeLists.txt, because this define comes from wxWidgets and should not be made inside kicad
Remove KICAD_GOST option because it is  now useless: the 2 GOST options are now selectable at run time and are:
* specific page layouts (now user definable, and the GOST page layouts are available in template folder)
* notation for multiple parts per package (made in eeschema, preference menu)

* Pre-built binaries for OpenSSL can be used from the LuaDist project: https://github.com/LuaDist/openssl/releases
* Building of Boost libraries fixed for Mingw-w64 for github plugin

Removed some Microsoft Visual C centric definitions in CMakeModules/config.h.cmake which were tripping up the mingw-w64 build

Enhance IO_MGR::GuessPluginTypeFromLibPath() to support the GITHUB plugin.
Build boost with -fPIC on Linux unconditionally, in preparation for
DLL/DSO build of kicad.
Add python script to test back to back reads of GITHUB plugin.

BUILD_GITHUB_PLUGIN will build GITHUB_PLUGIN on Linux now.  Don't know if the parser works yet, but the FootprintEnumerate() function worked in testing.

* Remove defined CMAKE_INSTALL_PREFIX for Windows from main CMakeList.txt.
* Move footprint library path detection code from pcbnew.cpp to EDA_APP
  object.
* Add CMAKE_INSTALL_PREFIX to config.h.cmake.
* Simplify and fix search path list code.
* Add CMAKE_INSTALL_PREFIX to the list of search paths in case KiCad was
  installed using `make install`.
* Add default global footprint library table to CMake install.
* Add method to set footprint library table to PCB_BASE_FRAME object.
* Remove unused function EDA_APP::GetLibraryFile().
* Minor FP_LIB_TABLE object improvements.

Lay basis for a more full featured usage of boost, including compiled libraries such as unit_test_framework, system, etc.  Move headers now into boost_root/include/boost/.

REMOVE: USE_PCBNEW_NANOMETERS by making it the only way to go in pcbnew, effectively removing the deci-mils build.

* Added modified CMake FindPython... modules to support using Python-a-mingw-us distribution when building Windows scripting support using MinGW

*) Enhancements to make_lexer().
*) Support multi-threaded build.
*) Switch to "bzr patch" from patch.exe for Windows users.

   File "rules" has instructional text as comments near top.

2) Convert all text files in repo to LF line ending form.
   Any checkout done with "rules" in play will convert the working
   tree to native line ending, while keeping repo as LF line ending.

Add CheckCXXSymbolExists.cmake to fix configure bug using CMake versions prior to 2.8.6. (fixes lp:1124854)
