Yes, on the desktop pkg-config --cflags glesv2.pc shows nothing.
But the generated cmake code for desktop Qt5 does not have the
find_package() command which fails when cross-compiling.
(And I don't wanna figure out why the cmake file is different
for the desktop).

The pkg-config used by buildroot lists the path in sysroot.

Anyway, seems Cflags: -I${includedir} is the minimum for all
GL config files.
