Are you sure your scratch build corresponds to the linked spec file?
The spec file reads:
%ifarch x86_64
-DEMBREE_MAX_ISA=SSE4.2 \
%else
-DEMBREE_MAX_ISA=NONE \
%endif
but the build.log shows:
+ /usr/bin/cmake -DCMAKE_C_FLAGS_RELEASE:STRING=-DNDEBUG
-DCMAKE_CXX_FLAGS_RELEASE:STRING=-DNDEBUG -DCMAKE_Fortran_FLAGS_RELEASE:STRING=-DNDEBUG
-DCMAKE_VERBOSE_MAKEFILE:BOOL=ON -DCMAKE_INSTALL_DO_STRIP:BOOL=OFF
-DCMAKE_INSTALL_PREFIX:PATH=/usr -DINCLUDE_INSTALL_DIR:PATH=/usr/include
-DLIB_INSTALL_DIR:PATH=/usr/lib64 -DSYSCONF_INSTALL_DIR:PATH=/etc
-DSHARE_INSTALL_PREFIX:PATH=/usr/share -DLIB_SUFFIX=64 -DBUILD_SHARED_LIBS:BOOL=ON
-DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_STANDARD=17 -DCMAKE_INSTALL_LIBDIR=/usr/lib64
-DCMAKE_INSTALL_PREFIX=/usr -DEMBREE_COMPACT_POLYS=ON -DEMBREE_IGNORE_CMAKE_CXX_FLAGS=OFF
-DEMBREE_ISPC_SUPPORT=ON -DEMBREE_MAX_ISA=DEFAULT -DEMBREE_TUTORIALS=OFF
There is -DEMBREE_MAX_ISA=DEFAULT instead of -DEMBREE_MAX_ISA=NONE.
Morover, I'm not sure whether upstream supports a generic AArch64. README.md
reads:
Embree requires at least an x86 CPU with support for
SSE2 or an Apple M1 CPU.
The CMake file just specifies NEON so I suspect it's just generic but
has only been tested on M1 Mac
