lazarus for windows使用QT5要注意的事项

lazarus要使用QT5：
1、编译Qt5Pas1.dll，编译方法见：编译Qt5pas1.dll - 秋·风 - 博客园
2、设置lazarus project的LCLWidgetType为QT5

3、将QT5的关键dll拷贝到应用程序当前目录，以下是经测试验证后的核心文件：

libbrotlicommon.dll
libbrotlidec.dll
libbz2-1.dll
libdouble-conversion.dll
libfreetype-6.dll
libgcc_s_seh-1.dll
libglib-2.0-0.dll
libgraphite2.dll
libharfbuzz-0.dll
libiconv-2.dll
libicudt76.dll
libicuin76.dll
libicuuc76.dll
libintl-8.dll
libmd4c.dll
libpcre2-16-0.dll
libpcre2-8-0.dll
libpng16-16.dll
libstdc++-6.dll
libwinpthread-1.dll
libzstd.dll
Qt5Core.dll
Qt5Cored.dll
Qt5Gui.dll
Qt5Network.dll
Qt5Pas1.dll
Qt5PrintSupport.dll
Qt5Widgets.dll
zlib1.dll

 4、在应用目录建platforms和styles目录，将qwindows.dll拷贝到platforms,qwindowsvistastyle.dll拷贝到styles目录

如果缺少qwindows.dll或文件位置不对，会出现：

如果缺少styles目录及qwindowsvistastyle.dll，应用程序的控件样式比较土
