Allow building recipes outside haikuports tree

[X547]

It would be nice to allow haikuporter use system package info instead of info inside haikuports tree. It will allow use recipe files for various projects outside haikuports.

Just use the "package" tool directly if you are outside the tree. Cmake has support for it through cpack, for example.

What is the use of haikuporter in that situation?

[X547]

Many build systems can't build hpkg packages, for example Haiku makefile engine. haikuporter would simplify package generation.

Cmake has support for it through cpack, for example.

Is more info about building hpkg by cmake available?

[pulkomandy]

You set cpack_binary_generator as explained in https://cmake.org/cmake/help/v3.12/module/CPack.html#variable:CPACK_GENERATOR and set the othervariables as documented there. Then use "make package"

I can't see HPKG generator in cpack:

Generators
  7Z                           = 7-Zip file format
  DEB                          = Debian packages
  External                     = CPack External packages

  ZIP                          = ZIP file format

Which generator should I use?
cmake version is 3.16.0.

[pulkomandy]

Then it seems my work to add support for the hpkg format has been removed. I had even submitted them upstream: https://cmake.org/Bug/view.php?id=14788

[mmuman]

Looks like they moved their bugtracker…
https://gitlab.kitware.com/cmake/cmake/issues/14788

[mmuman]

But I don't see CPackHpkg mentionned in the history…

[X547]

Is it possible to include HPKG generator to haikuports patchset?

[pulkomandy]

Yes, and it would be great if we can ping cmake team to upstream it again, and if people would not remove my patches when they update cmake versions because "the new one compiles without the patches"

[X547]

I uploaded fixed patch for cmake 3.16.0: haikuports/haikuports#4673.
