More output from cmake

[miroi]

Hi,

would it be possible to have more output from autocmake (through verbose flag) ? I am used to the DIRAC cmake output, containing compiler flags, compiler versions, extra libraries...

   configure step is done
   now you need to compile the sources:
   $ cd build
   $ make

It is definitely possible. But the question is probably whether this should be provided by default and this I don't know yet. Everything that is on by default has to work for "all" possible projects. I suggest you start coding a module that does that and if it turns out general enough we include it in the standard set of modules.

I tried to emulate config_info output based on git_info output, but plenty of variables are undefined in the simplest test case (I modified fc).

So I leaving this issue. Probably good printout can be in done in own cmake module.

A warning about dealing with build info using header files. Sounds like a perfect idea and I have tried it myself but this will most probably fail on Fortran due to the line limit. This needs extra care and extra scripts that chop or truncate strings. Alternatively it requires Fortran calling C which includes the header file.
