弱问关于libxml2

[yccnankai]

REDEME上面是这么说的“The code generator plugin needs libxml2 and libxslt. The development
files are assumed to be in /usr/include/libxml2. Change this in
LA4.pro according to your configuration if you want to use the
code generator. If you use Debian GNU/Linux, it should be good with
lixml2-dev and libxslt-dev packages. “

在终端运行时产生如下错误：This program accepts one command line switch,which is the QTDIR to use.
**************************
Your QTDIR is /usr/share/qt3/
Please, ensure that it is pointing to the right directory
**************************
Executing: cd tools &&
Executing: tar -pzxf tmake.tar.gz
Executing: cd ..
Executing: tools/tmake LA4.pro >Makefile
Executing: rm -f tools/tmake
Executing: rm -rf tools/template
Success.
You can go on now and type 'make'

WARNING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
LA4 now needs libxml and libxslt for code generation.

By default, code generation is enabled.
If you want to compiles LA4 without it, see LA4.pro
for the lines to comment and uncomment before rerunning configure

Development files for libxml and libxslt should be placed
in /usr/include/libxml2.

请问这是什么意思？我已经安装了libxml2和libxslt，但是却不知道怎么在程序中链接它们，请教各位。本人很菜，请各位不令赐教。

需要开发包
sudo apt-get install libxml2-dev
