>Description:
libcmis fails to build as follows:

$ make
=> Bootstrap dependency digest>=20010302: found digest-20190127
=> Checksum SHA1 OK for libcmis-0.5.2.tar.gz
=> Checksum RMD160 OK for libcmis-0.5.2.tar.gz
=> Checksum SHA512 OK for libcmis-0.5.2.tar.gz
===> depends-message [libcmis-0.5.2nb9] ===> Installing dependencies for libcmis-0.5.2nb9
==========================================================================
The following variables will affect the build process of this package,
libcmis-0.5.2nb9.  Their current value is shown below:

        * SSLBASE = /usr
        * SSLCERTS = /etc/openssl/certs
        * SSLDIR = /etc/openssl
        * SSLKEYS = /etc/openssl/private

You may want to abort the process now with CTRL-C and change their value
before continuing.  Be sure to run `/usr/bin/make clean' after
the changes.
