Newbie on OpenCA's OCSP Responder setup

[StocktonC]

hi all,

i am newbie on OpenCA's OCSP Responder. I just assigned to develop an OpenCA's OCSP Responder project to test the verification of a certificate status. Refer to official website. I downloaded libpki-0.8.9.tar.gz and openca-ocspd-3.1.2.tar.gz and putty the files to new linux server (CentOS7) . After i run ./configure under libpki folder. It returns the following message:

checking checking for ldap vendor... LDAP VENDOR () ===> searching for Sun
checking checking for OpenLDAP vendor () ... LDAP VENDOR:
*** ERROR: No supported LDAP vendor found.
configure: error: *** ERROR: Do you have the devel package installed ?

I really don't know how to do. Looks there very limited setup document about that.
Did anyone can share me more update document about the setup?

Thanks.

above stated issued fix by run
=> yum install openldap-devel
but new issues come up with following message during run make command under libpki stage:

Now i face the same issue as all of others without a clear solution on that:

error: Failed dependencies:
libpki.so.89()(64bit) is needed by openca-ocspd-3.1.2-1.el7.x86_64
