You have not explicitly asked to use pkg-config [复制链接]

在做imx6的Qt交叉编译工作，对Qt4.8.7-open-source进行配置时，得到如下错误：

You have not explicitly asked to use pkg-config and are cross-compiling.
pkg-config will not be used to automatically query cflag/lib parameters for
dependencies

The tslib functionality test failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR and QMAKE_LIBDIR in

QMAKE_INCDIR 和 QMAKE_LIBDIR都已经在对应的qmake.conf文件中定义好了，请问会是什么问题呢?

谢谢！
