How do I link with a non platform .framework? (that is not in the systems framework folder)

[pjako]

I tried to add the Vulkan .framework file from https://vulkan.lunarg.com/sdk/home to a fips project. I just put the file in the fips project root and tried to use it with fips_frameworks_osx(vulkan) but that did not work, I guess that macro does not search in the project root.

I haven't tried it with OSX frameworks yet, but fips defines a set of standard directories where it searches for link libraries both in the main project and dependencies with the naming convention [proj]/lib/[platformname].

So you could try putting the Vulkan framework file into [proj]/lib/osx and see if cmake picks it up.

This is where the linker search path setup happens:

• for the main project: https://github.com/floooh/fips/blob/e4abb256caf23a48a37d1e418b2130f609540c0c/cmake/fips_private.cmake#L40
• for dependencies the standard locations are generated here: https://github.com/floooh/fips/blob/e4abb256caf23a48a37d1e418b2130f609540c0c/mod/dep.py#L348
• you can also export your own library search paths in the fips.yml file (for dependencies): https://github.com/floooh/fips/blob/e4abb256caf23a48a37d1e418b2130f609540c0c/mod/dep.py#L360
• and finally the lowest-level way to do it is directly via cmake, for instance here in the oryol fips-include.cmake: https://github.com/floooh/oryol/blob/2f8ea56c8c6611f92bce8871f3ac7de4eb887b3a/fips-include.cmake#L167

Tried to put the framework here: [project]/libs/osx/vulkan.framework did not works unfortunately

[floooh]

The name should be 'lib' not 'libs' (I know it should be 'libs')

[pjako]

ups... well tried it now with 'lib' still does not work using.. fips_frameworks_osx(vulkan) ./fips gen ... CMake Error: The following variables are used in this project, but they are set to NOTFOUND. ...

[floooh]

hmm the reason is probably that it's doing a find_library() here: https://github.com/floooh/fips/blob/e4abb256caf23a48a37d1e418b2130f609540c0c/cmake/fips_private.cmake#L64, I think this was necessary to make linking against system frameworks work.

Another thing you could try is simply a fips_libs(vulkan.framework), this does the same as fips_frameworks_osx() but without the find_library() call...

[pjako]

Now it does not work silently using (no error from ./fips gen) fips_libs(vulkan.framework)
