compiling error when "cmake3 -DCMAKE_BUILD_TYPE=Debug"

[wyang007]

I got the compiling error on centos 7 (devtoolset-7) when "cmake3 -DCMAKE_BUILD_TYPE=Debug ..". The error msg is :

In file included from /opt/rh/devtoolset-7/root/usr/include/c++/7/cassert:44:0,
from /tmp/xrootd/src/XrdCrypto/XrdCryptosslCipher.cc:35:
/tmp/xrootd/src/XrdCrypto/XrdCryptosslCipher.cc: In constructor ‘XrdCryptosslCipher::XrdCryptosslCipher(bool, int, char*, int, const char*)’:
/tmp/xrootd/src/XrdCrypto/XrdCryptosslCipher.cc:489:14: error: ‘DH_get0_p’ was not declared in this scope
assert(DH_get0_p(dhparms));
^
/tmp/xrootd/src/XrdCrypto/XrdCryptosslCipher.cc:489:14: note: suggested alternative: ‘DH_get0_pqg’

If I run cmake3 without the -DCMAKE_BUILD_TYPE=Debug, all will compile with no error.
