It took me some time to reproduce my previous issue.
libegl-mesa-dev is not installed in my system, while there are lib and dev
files in $WLD from mesa.
So egl check fails but it is still ok to build VA/Wayland.
It seems the following check doesn't respect $PKG_CONFIG_PATH
AC_CHECK_HEADERS([EGL/egl.h])
AC_CHECK_LIB(EGL, eglGetDisplay, [
USE_EGL="yes"
EGL_DEPS_LIBS="-lEGL"
])
So the patch is better to be:
diff --git a/configure.ac b/configure.ac
index dcd27fe..1bfe8cf 100755
--- a/configure.ac
+++ b/configure.ac
