set_target_properties called with incorrect number of arguments

[programmerq]

When building on a system missing expected CPU flags, it is actually possible for the CMakeLists.txt to never set the GGML_C_FLAGS variable. This causes this line to be called with no value:

ggml/tests/CMakeLists.txt

Line 143 in 43ffec5

set_target_properties(${TEST_TARGET} PROPERTIES COMPILE_FLAGS ${GGML_C_FLAGS})

Here are the flags from cpuinfo:

flags		: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx lm constant_tsc nopl xtopology cpuid tsc_known_freq pni cx16 x2apic hypervisor lahf_lm cpuid_fault pti

In my case, I simply chosen incorrect settings in my KVM vm, so I was able to reboot with the correct configuration. I still didn't expect a missing CPU flag to cause a compile error. At the very least, it should warn whether those flags are required. If they aren't it should build without them.

I am running into the same issue. What CPU flags did you need to modify for your KVM to get it working?
