If we build BhyveX64 with build -p /home/mjsbeaton/OpenSource/edk2/OvmfPkg/Bhyve/BhyveX64.dsc -a X64 -b DEBUG -t GCC5 (for example) then it builds correctly.

However the .dsc and .fdf files for this platform appear to support the compilation define SMM_REQUIRE, which defaults to FALSE.

If we build with build -p /home/mjsbeaton/OpenSource/edk2/OvmfPkg/Bhyve/BhyveX64.dsc -D SMM_REQUIRE -a X64 -b DEBUG -t GCC5 then the build fails. This is because multiple components required by the .fdf file when SMM_REQUIRE is TRUE are not defined in the .dsc file when SMM_REQUIRE is TRUE.

I don't have a strong opinion about whether BhyveX64 is supposed to include SMM support, but it does seem to be a bug to include incomplete support resulting in a broken build when activated, as now.
