catastrophic error: cannot open source file "openssl/opensslconf.h"

Hi,

I try to compile a c program which contains the only header file "openssl/opensslconf.h" and get the error: catastrophic error: cannot open source file "openssl/opensslconf.h". I find opensslconf.h in directory“/usr/include/x86_64-linux-gnu/openssl/”and link it with -l parameter. But it prints the same error. I am sure there are some solutions i don’t see , but knowledge in linux is low. Thanks in advance for your help.
