Add separate ExternalDependencies Xcode project.
Move external dependencies to ExternalDependencies project.
The fetchDependencies script builds external dependencies libraries into External/build.
The fetchDependencies script prepares SPIRV-Tools without preparing glslang.
MoltenVK links to pre-built external dependency static libraries.
MoltenVK includes external library headers using full relative paths.
Update to latest dependency libraries for Vulkan SDK 1.1.92.
Generate Hologram demo dispatch files in fetchDependencies and remove them from git.
Update MoltenVK version to 1.0.27.
Update What's New document.
Fixes to create_dylib.sh to cleanup bitcode and architecture support.
Update to latest SPIRV-Cross version.
Update MoltenVK version to 1.0.26.
Update Xcode projects to Xcode 10.1.
Update What's New document.
Add --v-headers-root, --spirv-cross-root,
and --glslang-root options with an arg that allow
caller to pass in the root dir of these three
repos if the caller already has them. The script
then symlinks to these instead of fetching and building.
Using a symlink to locate an externally-built glslang
doesn't work if the parent directory of the externally-built
glslang isn't the same as the parent here (External).
This fixes a portability warning when building from V-LVL
because the parent there was "external" vs "External".
Copy is still a win because it is better than fetching and
building.
Changes to fetchDependencies script:
- remove -sdk option
- Add --v-lvl-root and --glslang-root options (with an arg)
that allow caller to pass in the root dir of these two repos
if the caller already has them. The script then symlinks to
these instead of fetching and building.
Fixes: #79#84
fetchDependencies script now in top directory to avoid Travis caching of
External directory. fetchDependencies is now smart about fetching vs cloning
and building only what is necessary.
