Unsolved Cross compile QtBase for RaspberryPI CM3 without the raspberry toolchain

[dxvx]

Hello Everyone,
I have followed this Qt5 tutorial in order to build Qt5 for raspberry pi CM3.
Why all the time I want to try another compiler (like GCC9 from the latest ubuntu repo) the error is:

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.

the ./configure command is:

./configure -release -opensource -confirm-license -opengl es2 -no-use-gold-linker -v -nomake examples -nomake tests \
-device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=arm-linux-gnueabihf- \
-sysroot ~/workspaces/rasp10_cons_1 -prefix /opt/qt5 -extprefix ~/workspaces/qt/qt5-pi -hostprefix ~/workspaces/qt/qt5-tools

Many thanks in advice,
regards.

Have you succeeded with the toolchain suggested in that tutorial?

@Pablo-J-Rogina yes, I have already build qtbase and qtmultimedia with the toolchain reccomended by raspbian.
If I take the same command "./configure..." changing the default toolchain with another one I have the error.
I have already tested my toolchain building some test c and c++ programs.
