Subject: [PATCH] configure.ac: don't require eglmesaext.h
|
||||
|
||||
E.g. the Vivante EGL implementation does not provide eglmesaext.h.
|
||||
|
||||
The commit moves the check for header file existence outside of the
|
||||
check for existence of a egl packageconfig and makes the existence
|
||||
of eglmesaext.h optional.
|
||||
|
||||
fixes commit fb1acfec ("Fix building against libglvnd-provided EGL headers")
