Bug ID: 2007657
           Summary: Blender color management options not available
           Product: Fedora
           Version: 34
          Hardware: x86_64
                OS: Linux
            Status: NEW
         Component: blender
          Severity: medium

  Target Milestone: ---
    Classification: Fedora

Description of problem:

Using the Fedora 34 package (blender-2.93.4-1.fc34.src.rpm), all 'Color
Management' options under the 'Render Properties' are missing. Using the
blender.org download all options are found as expected.

A possinle cause:  
Upon starting the executable in a shell, error messages about color management
and OpenColorIO are produced. An RPM ChangeLog entry states:

* Wed Sep 01 2021 Richard Shaw  1:2.93.3-9
    - Rebuild for OpenColorIO 2.1.

Fedora 34, however, seems to provide OpenColorIO 1.1.1.

Version-Release number of selected component (if applicable):

2.93.4-1.fc34

How reproducible:

Steps to Reproduce:
1. Start package provided Blender
2. Navigate to Render Options (by default right-side lower section, 2nd tab
from top), scroll to end of tab, expand Color Management
3. Click on View Transform, note multiple missing options (e.g. Filmic)
4. Click on Look, not multiple missing options
5. Build a scene and attempt to modify Exposure, Gamma; note lack of change
(use viewport shading: rendered)

Actual results:

Multiple missing options and functionality under Color Management.

Expected results:

View Transform dropdown should contain False Color, Raw, Filmic, Filmic Log,
Standard. Look dropdown should contain multiple contrast options. Exposure,
Gamma sliders should affect (rendered shading) lighting.

Additional info:

Suspected culprit: package compiled against OCIO 2, F34 supplies OCIO 1.  
(Separately, Blender has previously encountered problems with paths containing
more exotic UTF-8 characters, leading to similar problems when required data
files are not found, but this presumably is not the issue here.)
