OpenEXR has some dependecies that other other modules in Blender
requires. When disabling OpenEXR these dependecies could not match
and building blender would fail.
This PR disables the next options when `WITH_IMAGE_OPENEXR=Off`
- `WITH_OPENVDB`
- `WITH_ALEMBIC`
- `WITH_VULKAN_BACKEND`
- `WITH_CYCLES_OSL`
Additionally windows stores the IMath libraries in `IMATH_LIBRARIES`
Linux and Mac stored the IMath libraries in `IMATH_LIBRARY`. This
change will also adds `IMATH_LIBRARIES` variable to all platforms.
Pull Request: https://projects.blender.org/blender/blender/pulls/106209
Building against the existing 3.1 libraries should continue to work, until
the precompiled libraries are committed for all platforms.
* Enable WebP by default.
* Update Windows for new library file names.
* Automatically clear outdated CMake cache variables when upgrading to new
libraries.
* Fix static library linking order issues on Linux for OpenEXR and OpenVDB.
Implemented by Ray Molenkamp, Sybren Stüvel and Brecht Van Lommel.
Ref T95206
FindOpenEXR was updated to find new lib names and separate Imath. It's all
added to the list of OpenEXR include dirs and libs.
This keeps it compatible with both version 2 and 3 for now, and doesn't
require changes outside the find module.
Ref D14128
Search for all potential library names in each directory, otherwise e.g.
libImath-2_2.a from a system directory will be preferred over libImath.a even
if we specified a directory.
Reduce the number of possible locations used to find libraries,
to simplify troubleshooting.
Only keep '*_ROOT_DIR' and the path used by 'install_deps.sh'.
Weird library names having version suffix (e.g. libIex-2_1.so) are used only
when the OpenEXR was built with CMake. Building the library with the Autotools
doesn't add the version suffix.
Note that I also updated OpenEXR to 2.1.0 (and updated our CMake openexr module as well).
Users will have to update their build settings as told by the script (also in BUILD_NOTES.txt generated file)!
Note I removed all ugly patches from this script, we are currently using custom git repo for OpenEXR/OIIO/OSL,
hopefully we will soon be able to use vanillia code from official repos!
As OSL headers mix #include <OpenEXR/foo.h> and #include <foo.h>, we need both /path/to/openexr/include and /path/to/openexr/include/OpenEXR include paths... :/
Issue investigated by doug65536 on IRC, thanks.
made some small edits
- removed changes to AVI reading since the data types are apart of the format spec.
- absf -> abs for a double value in render code.
