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.
