Transitive constraints are not properly considered in multiple output recipes #3308
Description
Transitive package constraints from a sub-package do not appear to be considered when rendering recipes with multiple outputs. This can result in an unnecessary UnsatisfiableError during the build.
For example for a recipe with two outputs:
package:
name: foo_split
version: 1.0.0
outputs:
- name: libfoo
requirements:
host:
- openssl
- name: foo
requirements:
host:
- python
- {{ pin_subpackage('libfoo', exact=True) }}Attempting to pin openssl to anything but the latest version will result in foo failing to build. For example with the following CBC.yaml file:
openssl:
- 1.0.2
python:
- 3.6The recipe renders as:
$ conda render .
read filter "zstd" is not supported
write filter "zstd" is not supported

Notice that in the second recipe openssl 1.1.1a is in the host section which will conflict with openssl constraint introduced by libfoo 1.0.0 via a run_export.
Building the recipe fails when solving an environment for the build of foo:
$ conda build .
