Cross-compilation failed due to undefined references

Hi everybody,
I am trying to cross-compile Qt 5 for the Raspberry Pi 3 model B. I followed this article from the wiki but also checked out this and this ones.
I tried with multiple versions of Qt: 5.15.3, 5.15.2 and 5.12.12 but all of these end up giving me the following error during the build:/usr/bin/arm-linux-gnueabihf-g++ -mfloat-abi=hard

sysrootdirectory since I doubted some library could have been missed by rsync but nothing changed.
Any clue?
Also the EGLFS, which is quite crucial, is always disabled by the configure script:QPA backends: DirectFB ............................... no EGLFS .................................. no LinuxFB ................................ yes VNC .................................... yesThanks in advance!
