Shouldn't be "temporary" just "not in cache".

I don't think you should.
Looks like a bug to me, how come CMAKE_SIZEOF_VOID_P
would it be defined "sometimes" but not **always**...
need to dive into the source of this definition, may be it is not always
defined because it is "indirectly" defined in the chain of CMake processing due
to CMake cache.
By the way shouldn't you use
if (CMAKE_SIZEOF_VOID_P EQUAL 8)
instead of
if ( "${CMAKE_SIZEOF_VOID_P}" EQUAL "8" )
from the doc I think EQUAL is for values whereas STREQUAL is for string.
