Package: blender Version: 2.81.a+dfsg-5 Severity: normal It looks like blender needs libegl-dev (containing a libEGL.so symlink to libEGL.so.1 from libegl1 package), to build correctly.
The libegl-dev is suggested by some other packages, during build process, but it is not explicitly installed. This makes build fail during cmake stage, for example on alpha and kfreebsd-i386 archs. https://buildd.debian.org/status/fetch.php?pkg=cmake&arch=alpha&ver=3.15.4-1&stamp=1579830052&raw=0 Regards, Witold
