Hey
I'm working on a Cmake script that would allow me to build 2 binaries
for my app using 2 different architectures.
For this I've decided to have 2 Brew's on my system. I've gone with brew
as vcpkg does not support openimageio for arm, or intel. Cant remember.
1. Intel
2. Arm
Now this approach worked with openSSL, my flags can build both intel and
arm bundle, but when it comes to openimageio I cant include it no matter
what I try :/
In general I have something like
```
if(FLAG_BUILD_INTEL)
set(BREW_ROOT "/usr/local/Cellar/")
set(CMAKE_OSX_ARCHITECTURE "x86_64" CACHE INTERNAL "" FORCE)
else()
set(BREW_ROOT "/opt/homebrew/Cellar/"
set(CMAKE_OSX_ARCHITECTURE "arm64" CACHE INTERNAL "" FORCE)
endif()
```
then I try to do
```
set(OpenImageIO_ROOT_DIR
${BREW_ROOT}openimageio/2.3.16.0/lib/cmake/OpenImageIO)
and then
find_package(OpenImageIO CONFIG REQUIRED)
and 50x other things. No matter what I do, he either finds openimage but
set it to "FALSE" or he finds it but when I compile I end up with:
Undefined symbols for architecture arm64. Or x86_64.
No matter what I do when I do
message(${OpenImageIO_DIR})
it is always the same directory. I can not tell my cmake, to use
openimage from either Brew Intel or Brew ARM.
Its weird that even as is, my app wont compile for arm either, (it
should) but for now I've no idea how to bite it.
Has any1 done any cross compiles? How did u solve arm/intel targetting?
Regards
Dariusz
