Building openssl outside of the source tree" doesn't work well

I tried exactly that just now, exactly same 'obj' ubdirectory, and it
works with no problem.

Something I'm noticing from your command line is that all -I options
that I expect to see there are gone.  This is what I expect (note that
I go directly at the object file for demonstration purposes):

    : ; make apps/libapps-lib-app_rand.o 
    gcc  -I. -Iinclude -Iapps/include -I.. -I../include
    -I../apps/include  -fPIC -pthread -m64 -Wa,--noexecstack -Wall -O3
    -DOPENSSL_USE_NODELETE -DL_ENDIAN -DOPENSSL_PIC
    -DOPENSSL_CPUID_OBJ -DOPENSSL_IA32_SSE2 -DOPENSSL_BN_ASM_MONT
    -DOPENSSL_BN_ASM_MONT5 -DOPENSSL_BN_ASM_GF2m -DSHA1_ASM
    -DSHA256_ASM -DSHA512_ASM -DKECCAK1600_ASM -DRC4_ASM -DMD5_ASM
    -DAES_ASM -DVPAES_ASM -DBSAES_ASM -DGHASH_ASM -DECP_NISTZ256_ASM
    -DX25519_ASM -DPOLY1305_ASM -DOPENSSLDIR="\"/usr/local/ssl\""
    -DENGINESDIR="\"/usr/local/lib/engines-3\""
    -DMODULESDIR="\"/usr/local/lib/ossl-modules\"" -DNDEBUG  -MMD -MF
    apps/libapps-lib-app_rand.d.tmp -MT apps/libapps-lib-app_rand.o -c
    -o apps/libapps-lib-app_rand.o ../apps/app_rand.c

So the question is what happened to '-I. -Iinclude -Iapps/include
-I.. -I../include -I../apps/include' in your build.

I cannot say right now, but it might help if you show the output from
'./configdata.pm --dump'

Cheers,
Richard
