Solved Build Qt 5.14.2 on Ubuntu 18.04

I try to build Qt 5.14.2 on Ubuntu 18.04
The packages:
sudo apt install gcc
sudo apt install build-essential
sudo apt install freeglut3-dev
sudo apt install mesa-utils
sudo apt install mesa-common-dev
sudo apt libgl1-mesa-dev
sudo apt libglu1-mesa-devAlready installed and upgraded.
QT configured with:
./configure -prefix $PWD/qtbase -opensource -skip qtwebengine -skip qtquickcontrols -skip qtconnectivity -no-icu -skip qtwebglplugin -skip qtlocation -no-sql-odbc -no-sql-sqlite -nomake examples -nomake tests -opengl desktop -platform linux-g++-64Nonetheless:
ERROR: Feature 'opengl-desktop' was enabled, but the pre-condition '(config.win32 && !config.winrt && !features.opengles2 && (config.msvc || libs.opengl))
|| (!config.watchos && !config.win32 && !config.wasm && libs.opengl)' failed.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.How to fix that?

Fixed it with:
#QMAKE_LIBDIR_OPENGL = /usr/X11R6/lib64
QMAKE_LIBDIR_OPENGL = /usr/libin
/qtbase/mkspecs/linux-g++-64/qmake.conf
then run
./configure -recheck-all
