Well, I think I figured out a way to decouple them. If there are strong requirements on supporting the non-cmake usecase, I can try to work it out.

Yes. The manifest tool is now fully replying on CMake (it has been, since I introduced the conditional parsing of manifests around half a year ago). It needs to be aware of the build configurations.

Hey Kevin
Does this mean that cmake will be required to generate the headers/etc from the manifests?
I believe in the past we deliberately supported the non-cmake usecase, as some people were building TF-M in alternate ways.

Hi,
Is there anyone using environment variables for the "manifest" attribute in out-of-tree manifest lists? I'm asking because I'm working to support configurable stack_size for Secure Partitionshttps://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/15155. In the patch the support of environment variables in manifest lists is removedhttps://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/15155/1/tools/tfm_parse_manifest_list.py#b256. Because I have to call the CMake command configure_file to replace the stack_size symbols (CMake variableshttps://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/15155/1/secure_fw/partitions/crypto/tfm_crypto.yaml#15 surrounded with "@") with their values. While configure_file does not recognize environment variables.
If you do have environment variables in manifest list, there is an alternative: Replace the env. variables with CMake variables surrounded with "@" and set the value of the CMake variables in either config files or command line inputs.
Best Regards, Kevin
