Building a cmake-based package

[Ryan Schmidt]

Being a question about how to develop Portfiles, this thread should occur on the macports-dev list, not the macports-users list.

In the top part of the Portfile, after the "PortSystem 1.0" line, add the line "PortGroup cmake 1.0". This will add a cmake build dependency, set up the configure phase to run cmake instead of ./configure, and in other ways set the port up for standard cmake operating procedure. The cmake portgroup is not described in the MacPorts Guide, so I also recommend you just read the cmake-1.0.tcl source file to see what all it does for you.

Then in the configure area of the Portfile, you can add the line:

configure.args-append -G 'Unix Makefiles'

if that is truly required. (Try it without that line first and see what happens.)
