I guess the internal CPU test is run on the build system (if not
overridden), so on my x86 system it seems to be unset:
//Test have_mfpu_neon
have_mfpu_neon:INTERNAL=

In such cases it is possible to override by:
$ cmake -Dhave_mfpu_neon=1 ..

Or if it is required to have it forced on in such cases the
if condition could be modified to:
if(have_mfpu_neon OR NOT DEFINED have_mfpu_neon OR have_mfpu_neon MATCHES "^$")

I.e. to be forced on if unset or undefined
