BUILD=debug
編譯調試版本，因為加入了調試信息，所以文件比較大。
  Builds debug version of the library (default is 'release'). This affects
  name of the library ('d' is appended), __WXDEBUG__ is defined and debug
  information compiled into object files and the executable.

SHARED=0
生成動態鏈接庫的版本。動態鏈接庫是很有用的，特別是使用LGPL的開發庫的時候，都要變成動態庫，才可以商業用。
  Build static libraries instead of DLLs. By default, DLLs are built
  (SHARED=1).

UNICODE=1
本人是中國人，自然要選這個，就是學的時候要注意的東西多一寫，但總比以后不習慣強。
  To build Unicode versions of the libraries, add UNICODE=1 to make invocation
  (default is UNICODE=0). If you want to be able to use Unicode version on
  Windows9x, you will need to set MSLU=1 as well.

  This option affect name of the library ('u' is appended) and the directory
  where the library and setup.h are store (ditto).

WXUNIV=1
就是不讓wx使用native的樣式，使用統一的樣式——跟人感覺不好看，但是后項開發的時候會比較方便，以為不用考慮各種gui元素的定位引起問題了。
  Build wxUniversal instead of native wxMSW (see
  http://www.wxwidgets.org/wxuniv.htm for more information).

Advanced options
----------------

MONOLITHIC=1
把所有的庫都變在一個文件中。
  Starting with version 2.5.1, wxWidgets has the ability to be built as
  several smaller libraries instead of single big one as used to be the case
  in 2.4 and older versions. This is called "multilib build" and is the
  default behaviour of makefiles. You can still build single library
  ("monolithic build") by setting MONOLITHIC variable to 1.

USE_GUI=0
不用gui模式，編寫命令行的程序。
  Disable building GUI parts of the library, build only wxBase components used
  by console applications. Note that if you leave USE_GUI=1 then both wxBase
  and GUI libraries are built. If you are building monolithic library, then
  you should set wxUSE_GUI to 1 in setup.h.

USE_OPENGL=1
自帶opengl支持
  Build wxmsw25_gl.lib library with OpenGL integration class wxGLCanvas.
  You must also modify your setup.h to #define wxUSE_GLCANVAS 1. Note that
  OpenGL library is always built as additional library, even in monolithic
  build!

USE_ODBC=1
自帶odbc支持
  Build two additional libraries in multilib mode, one with database
  classes and one with wxGrid database support. You must
  #define wxUSE_ODBC 1 in setup.h

USE_HTML=0
不用html庫
  Do not build wxHTML library. If MONOLITHIC=1, then you must also
  #define wxUSE_HTML 1 in setup.h.

USE_XRC=0
不用xrc庫。xrc是wx為了避免在不同的gui系統上程序元素之間的配合特別是定位的問題而提供的基于XML的用戶界面標記語言，通過定義不同系統上不同的xml樣式，來解決問題，有點類似于換膚。和xul還有xaml有點類似。
  Do not build XRC resources library. If MONOLITHIC=1, then you must also
  #define wxUSE_HTML 1 in setup.h.

RUNTIME_LIBS=static
不太明白。
  Links static version of C and C++ runtime libraries into the executable, so
  that the program does not depend on DLLs provided with the compiler (e.g.
  Visual C++'s msvcrt.dll or Borland's cc3250mt.dll).
  Caution: Do not use static runtime libraries when building DLL (SHARED=1)!

MSLU=1
不是像找麻煩開發win98程序的人就不用管了。
  Enables MSLU (Microsoft Layer for Unicode). This setting makes sense only if
  used together with UNICODE=1. If you want to be able to use Unicode version
  on Windows9x, you will need MSLU (Microsoft Layer for Unicode) runtime DLL
  and import lib.  The former can be downloaded from Microsoft, the latter is
  part of the latest Platform SDK from Microsoft (see msdn.microsoft.com for
  details). An alternative implementation of import library can be downloaded
  from http://libunicows.sourceforge.net - unlike the official one, this one
  works with other compilers and does not require 300+ MB Platform SDK update.

DEBUG_FLAG=0
DEBUG_FLAG=1
  If set to 1, define __WXDEBUG__ symbol, append 'd' to library name and do
  sanity checks at runtime. If set to 0, don't do it. By default, this is
  governed by BUILD option (if 'debug', DEBUG_FLAG=1, if 'release' it is 0),
  but it is sometimes desirable to modify default behaviour and e.g. define
  __WXDEBUG__ even in release builds.

DEBUG_INFO=0
DEBUG_INFO=1
  Same as DEBUG_FLAG in behaviour, this option affects whether debugging
  information is included in the executable or not.

VENDOR=<your company name>
  Set this to a short string identifying your company if you are planning to
  distribute wxWidgets DLLs with your application. Default value is 'custom'.
  This string is included as part of DLL name. wxWidgets DLLs contain compiler
  name, version information and vendor name in them. For example
  wxmsw250_core_bcc_custom.dll is one of DLLs build using Borland C++ with
  default settings. If you set VENDOR=mycorp, the name will change to
  wxmsw250_core_bcc_mycorp.dll.
