If my app requires relinking, then at link time
I would like to capture the current date and time and place it
in a last-minute source file which is linked with the application.
Following is my attempt at this with CMake.
This is just OTTOMH, but could you have something like this:
#include <string>
const std::string link_date( __DATE__ );
const std::string link_time( __TIME__ );
in a separate blah.cc file? Then set the "blah" target to one of the
PHONYs in the Makefile (those are the ones that always recompile
regardless, right?), and make sure it's a requirement for every link.
Dear Fatman:
One of the key points here is "If the app needs relinking...".
The link_date file can not cause the app to be relinked, but
if it IS relinked, you want to use an up-to-date version which
captures the current date and time of the link.
I like the use of __DATE__ and __TIME_ though.
Those will probably be a part of the final, portable solution.

Not sure how else you could accomplish this.
