No problem!

My system is similar: Debian testing with the OpenSSL 1.1.1d from the distribution. I have no build problems whatsoever. OpenSSL comes with backward compatibility macros that most allow code written for 1.0.2 to be compiled without errors. These macros can be turned off by changing the API compatibility version using -DOPENSSL_API_COMPAT=<version>.

You can check this with

    make V=1 imap-send.o

This will show the compiler command executed:

    gcc -o imap-send.o -c -MF ./.depend/imap-send.o.d -MQ imap-send.o
-MMD -MP   -g -O2 -I. -DHAVE_SYSINFO -DGIT_HOST_CPU="\"x86_64\""
-DHAVE_ALLOCA_H -DUSE_CURL_FOR_IMAP_SEND -DSHA1_DC
-DSHA1DC_NO_STANDARD_INCLUDES -DSHA1DC_INIT_SAFE_HASH_DEFAULT=0
-DSHA1DC_CUSTOM_INCLUDE_SHA1_C="\"cache.h\""
-DSHA1DC_CUSTOM_INCLUDE_UBC_CHECK_C="\"git-compat-util.h\"" -DSHA256_BLK
-pthread -DHAVE_PATHS_H -DHAVE_STRINGS_H -DHAVE_DEV_TTY
-DHAVE_CLOCK_GETTIME -DHAVE_CLOCK_MONOTONIC -DHAVE_GETDELIM
'-DPROCFS_EXECUTABLE_PATH="/proc/self/exe"'  -DFREAD_READS_DIRECTORIES
-DNO_STRLCPY -DSHELL_PATH='"/bin/sh"' -DPAGER_ENV='"LESS=FRX LV=-c"'
imap-send.c

Check it for any -D flags mentioning OpenSSL.

You can get even more verbose output from gcc by copying the compiler command make displays and running it after appending the verbose flag "-v" at the end.

Check this new output for include directories etc. You need to make sure that gcc picks up the system OpenSSL include files. They should be found under /usr/include/openssl.

Hope this helps,
