OpenEXR headers not found

It couldn’t find the <OpenEXR/ImathVec.h> in the downloaded library.

build log:

I have OpenEXR installed in pacman as well.

odds are the download got interrupted, svn does that some times, in /home/shin/blender-git/lib/linux_centos7_x86_64 run svn cleanup followed by svn update repeat until it successfully completes.

cleaned and updated the libraries.

Updating ‘.’:
At revision 62631.

tried building again but the same error occurred
