Add /usr/lib64 as a valid path to open libamdsmi.so

[zhguo01]

Binary amd-smi will search /usr/lib/ and current folder for loading libamdsmi.so:

#cat smi-lib/cli/cpp/src/host/smi_cli_api_host.cpp
...
#elif __linux__
	amdSmiLibHandle = dlopen("/usr/lib/libamdsmi.so", RTLD_NOW | RTLD_GLOBAL);
	if (amdSmiLibHandle == NULL) {
		amdSmiLibHandle = dlopen("./libamdsmi.so", RTLD_NOW | RTLD_GLOBAL);
	}
#endif

However, if we want to package gim driver, libamdsmi.so and amd-smi together into a rhel rpm, I think path /usr/lib64/ needs to be included into smi_cli_api_host.cpp, thus in the rpm spec file I could use the desired way for packaging:

mkdir -p %{buildroot}%{_libdir}
install -m 755 smi-lib/build/amdsmi/package/Release/amdsmi/libamdsmi.so %{buildroot}%{_libdir}
mkdir -p %{buildroot}%{_bindir}
install -m 755 smi-lib/cli/cpp/build/amd-smi %{buildroot}%{_bindir}

This will be fixed in the next release.

We have added make install targets to amd smi lib and tool as part of 8.3.0.K, you can control the install target using the usual $DESTDIR and $PREFIX variables. We also adjusted the loading logic to use the system default (i.e. first try loading "libamdsmi.so" without a path), so /usr/lib64 should work on distros that support it.

Also as part of dkms package we are now installing amd smi to /usr/local automatically
