APR and apr-util are required dependencies.

So - before creating httpd on Mac,

set APR port

install apr-util port

It is resolved.

In addition, you may need to set the variable 'OPENSSL_ROOT_DIR' to '/ opt / local'. You can do this by supplying '-DOPENSSL_ROOT_DIR = / opt / local' as the command line argument when running cmake.
