编译GDAL支持MySQL

GDAL支持MySQL需要MySQL的库才可以，编译很简单，修改nmake.opt文件中对应的MySQL的库的路径和lib即可。
nmake.opt文件中397行左右，如下：

# MySQL Libraries
# NOTE: Need /MT instead of /MD, also enable /EHsc switch. 
#MYSQL_INC_DIR = D:SoftwareMySQLServer4.1include
#MYSQL_LIB = D:SoftwareMySQLServer4.1liboptlibmysql.lib advapi32.lib

修改为：

# MySQL Libraries
# NOTE: Need /MT instead of /MD, also enable /EHsc switch. 
MYSQL_INC_DIR = F:WorkGDALgdal_needMySQLinclude
MYSQL_LIB = F:WorkGDALgdal_needMySQLliblibmysql.lib advapi32.lib

然后重新编译即可。
需要注意的是，将MySQL的dll要拷贝到gdalxx.dll所在的目录。
