SRTP ./ configure error?

When I configure asterisk as SRTP and with cyrpto so I get this error message when I made ./configure --with-srtp and --with-cyrpto
Error message is:
configure ***** The SRTP installation appears to be missing or broken
configure ******…
configure ***** including --without-srtp

How can I fix this problem?
I have downloaded OpenSSL library and compiled by myself manually. Maybe can be cause of this?

For SRTP in Asterisk, you’ll need libSRTP.
