glfw 3.4 linux build doesn't run doxygen in builddir/docs/html when a builddir is set.

I get this building on x86_64 and armv7l using cmake and -C builddir -DBUILD_SHARED_LIBS=ON using the current version of cmake (3.28.3):

Command "bash -c DESTDIR=/usr/local/tmp/crew/dest ninja -C builddir install" failed, retrying with "-j1"...                                                                                                   ninja: Entering directory `builddir'

Looking at my builddir/docs dir I see this:

ls glfw-3.4/builddir/docs
CMakeFiles  cmake_install.cmake  Doxyfile

It looks like doxygen is run in the glfw_source/docs/ directory and not in the builddir/docs/ directory.

Doxygen is definitely found:
