-Subject: [PATCH 4/4] scripts/template_dir: -[no]cmake flag for CMake module
- installation
-
-There are two issues with CMake module installation that are
-problematic for distro packages:
-1. the cmake module is installed under $HOME and this path is not overridable
-2. the path to SDK recorded in the cmake file is the same as the
-target directory, which might be prefixed by the staging path of the
-package build (e.g.  ~/mypackages/zerphyr-sdk/destdir/opt/zerphyr-sdk),
-not the final installation directory in the system (/opt/zephyr-sdk).
-
-1 is fixable by making the variable overridable from the environment:
-    : ${ZEPHYR_SDK_REGISTRY_DIR:=$HOME/.cmake/packages/Zephyr-sdk}
-(but this may be a bashism). But, 1 is not useful unless 2 is also
-addressed.
-
-2 might be fixable by introducing a prefix argument -p (default "") in
-addition to the target_dir (-d), and composing the destination directory
-for copying files as $prefix/$target_dir while using only $target_dir
-wherever installation paths are written, such as in the CMake module.
-
-Until 1 or 2 are addressed, add -[no]cmake arg so that the package
-scripts can install the CMake module themselves.
