不安装这些依赖库接下来运行configure的时候可能会报如下错误

WARNING: gperf is required to build QtWebEngine.

WARNING: bison is required to build QtWebEngine.

WARNING: flex is required to build QtWebEngine.

WARNING: host pkg-config not found

ERROR: The OpenGL functionality tests failed!
You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2],
QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.

如果发生类似这样的错 安装完相关依赖库之后 记得运行 rm config.cache来删除缓存的配置

./configure -prefix $PWD/qtbase -opensource -nomake examples -nomake testsmake -j 4make install
