1.下載安裝cmake，假設安裝路徑爲D:\Qt\cmake-2.8.10.2-win32-x86\
2.從QT菜單【Qt 4.8.3 Command Prompt】中進入命令行窗口，執行下面命令
set path=%path%;D:\Qt\cmake-2.8.10.2-win32-x86\bin
該命令行是設置cmake路徑
3.在qjson目錄下執行下面命令：
a).cmake -G "MinGW Makefiles" -DCMAKE_INSTALL_PREFIX=./
執行結果如下：

注意，cmake時，-G參數必須指定，否則會出現類似如下錯誤。網上大部分文章和readme文件也沒說明，本人由於此參數折騰了需求，不得已查文檔才解決問題。
CMake Error at D:/Qt/cmake-2.8.10.2-win32-x86/share/cmake-2.8/Modules/FindQt4.cm
ake:599 (message):
It appears you're trying to use Visual Studio with Qt built by mingw.
Those compilers do not produce code compatible with each other.
Call Stack (most recent call first):
CMakeLists.txt:35 (FIND_PACKAGE)
b).執行make，結果如下：

至此qjson已經編譯完成，頭文件和庫文件在lib目錄下，copy到自己工程下可以使用了。
