With the attached modified secure_fw/CMakeLists.txt and tools/tfm_parse_manifest_list.py files, I am able to redirect the generated files using the following command line:
python3 <full_path_to_your>/tfm_parse_manifest_list.py <full_path_to_your>/tfm_manifest_list.yaml <full_path_to_your>/tfm_generated_file_list.yaml <full_path_to_your>/<build_dir>
And then build the ConfigCoreIPC artifacts within <your_build_dir> using the following cmake line:
cmake -G"Unix Makefiles" -DPROJ_CONFIG=`readlink -f ../configs/ConfigCoreIPC.cmake` -DREMOTE_GEN_DIR=<full_path_to_your><build_dir> -DTARGET_PLATFORM=AN521 -DCOMPILER=GNUARM ../
The changes to tfm_parse_manifest_list.py are backward compatible with the standard usage.

Abishek,
Yes, we have modified tfm_gen.py and tfm_parse_manifest_list.py to support redirecting the destination of the generated template files into a command line provided destination build directory. A corresponding change to our platform's platform/ext/xyz.cmake file was also required to add the path to the root of the build directory to the embedded_include_directories() list as well as the paths to the generated linker command files.
I was not planning to provide these changes as a patch for review as I am very unsure of the applicability of this to other platforms. Also, I was fairly certain that given my very poor understanding of the CMake build system, my approach to the problem was not utilizing features present in CMake that would make the job simpler and more extensible.
Since the topic came up at the conference and you already seemed willing to address the out-of-tree build problem that the templates lead to, I assumed you folks would find a simple and elegant solution that would save me the embarrassment of exposing my lack of CMake expertise.

Hi Alan, Not sure if I remember the exact detail from the workshop last week, but did you mention that you have a prototype for this? If so, are you planning to push a patch for review? Thanks, Abhishek

Please modify the template generators to support out of tree build, and modify the CMake files to add the necessary include paths so that the files that include the template-generated files can find them.
