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.

Check config.log for details.

I find there is no change when i edit the mkspec of my platform, then i specify my platform manually by add param
"-platform linux-g++-64" then the problem solved.

@wegatron This means you don't have an opengl installed on your BB or in your sysroot. Or you passed incorrect parameters to your ./configure.

I experienced the same configuration error and the solution worked for me too, but in my case I was just trying to configure with -opengl es2. So, there was no cross compiling involved, but still, appending -platform linux-g++-64 made it work.

I'm working with the dev branch from git, so it's showing 5.11.0 as the version.

For the record, I was getting this error on my linux mint 19.1 Tessa addition. Adding the -platform linux-g++64 command fixed the problem.

Same problem here, cross-compiling Qt 5.12.8 (EGLFS support only) for BBB on Kubuntu 19. After spending hours in trying to debug the problem, I found this topic on the forum: just adding -platform linux-g++-64 fixed the problem... simply crazy!
