English:
I found a little bug in QtCreator 3.4.2 while I using a wizard to import external libraries to project.(after I tried 3.6.0, but it still has this bug)
When I using an absolute path to import libraries, the PRO file will add a "$$PWD/" before the path.
Then I may receive a "No such file or directory" error in import path while compiling.
then I must remove "$$PWD/" in LIBS, INCLUDEPATH and DEPENDPATH to fix this issue:

Before: LIBS += -L$$PWD/D:/Program/SomeComponenties/lib -lSCLIB #LINK ERROR
After: LIBS += -LD:/Program/SomeComponenties/lib -lSCLIB #SUCCESS

Chinese:
在使用QtCreator 3.4.2使用添加库向导导入一个使用绝对路径的外部库的时候PRO文件依然会加入"$PWD/"在这个绝对路径的前面, 这会导致在连接的时候编译器会找不到库文件从而编译失败, 必须删除PRO工程文件的LIBS, INCLUDEPATH和DEPENDPATH行前的"$PWD/"才能正常编译.
请产品经理注意一下这个Bug, 如果QtCreator修复了此Bug, IDE将会更好.
