* cmake : add config version support (wip) [no ci]
This commit adds support for find_package using a version, for example:
```
find_package(ggml 0.19.0 REQUIRED)
```
examples/test-cmake has been updated to use this and build scripts have
been added to verify this manually. This is still a work in progress and
I'm not sure about the scripts and if we can find better ways to test
this but it might be useful to have for verification of changes to the
cmake build.
* cmake : add semver to ggml backends [no ci]
This commit adds a semver to the ggml backend modules files.
The motivation for this is that the backends are currently loaded just a
file extension, for example .so on linux. With the introduction of
semantic versioning installing a new version should just work but since
these files don't have a version they would get overwritten. Adding the
semver to the library names allows multiple version to be supported and
the correct one will be loaded by the code.
I've only tested this on linux and need to test on mac and win.
* Revert "cmake : add semver to ggml backends [no ci]"
This reverts commit 53a6c58a07591951324c891b9986b2cffe5c7972.
* examples : update build-install.sh and set GGML_BACKEND_DIR
- Use OpenMP to parallelize iq2xs_init_impl and iq3xs_init_impl.
- Move the OpenMP detection from ggml-cpu to ggml-base.
- Update OpenMP dependencies in ggml-config.cmake.in.
* cmake: Add GGML_BACKEND_DIR option
This can be used by distributions to specify where to look for backends
when ggml is built with GGML_BACKEND_DL=ON.
* Fix phrasing
* CMake config: Create target only once
Fix error on repeated find_package(ggml).
For simplicity, check only for the top-level ggml::ggml.
* CMake config: Add CUDA link libs
* CMake config: Add OpenCL link libs
* CMake config: Use canonical find_dependency
Use set and append to control link lib variables.
Apply more $<LINK_ONLY...>.
* CMake config: Wire OpenMP dependency
* Fix dependencies between ggml and backends
ggml backends link only to ggml-base and ggml links to all backends.
* Fix installation of ggml backends
Set up GNUInstallDirs before setting the installation directory of ggml backends
