Actual outcome: build fails with:

configure: error: Package requirements (egl) were not met:
Package egl was not found in the pkg-config search path.
Perhaps you should add the directory containing `egl.pc'
to the PKG_CONFIG_PATH environment variable
Package 'egl', required by 'world', not found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables EGL_CFLAGS
and EGL_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
