Compiling issue Ubuntu 22.04

[goetzmoritz]

Hi there,

we are trying to compile on Ubuntu 22.04 with all dependencies (USD, openexr, imath) installed but still get an error:

~/RadeonProRenderUSD/build$ cmake ..

-- Configuring incomplete, errors occurred!

half.h is present in /usr/local/include/Imath/
openexr is also present in /usr/local/include/OpenEXR

Both versions are cloned and compiled today.

Any help with that? Thanks!

Could you please tell which version of USD you use? We had this issue with some versions, but it seems there are still versions we're not support

@goetzmoritz, please try PR #660. It should solve this problem

[peterurbanec]

USD 23.11 uses OpenEXR 3.1.11 which does not provide a Half library.

I also have this issue and #660 didn't solve it.
