this variable holds a list of files of cake-depends-db files. They contain lines like
cake_depends_db_add([URL ] [NAME ] CODE "cake_pkg(INSTALL URL ")

it holds a list of files of NAME -> URL informations like
set(CAKE_PKG_URL_OF_ZLIB http://github/zlib?branch=foo&BAR=bar)
CAKE_PKG_NAME_URL_DB_ZLIB ?

When cakepkg called from command line without valid CMAKE_INSTALL_PREFIX the default is not set and the check at the end of CakeLoadConfig.cmake allows it since the same code runs when only cake is called which does not need CMAKE_INSTALL_PREFIX

The main problem is that the same config file is used by both the cake and cakepkg while they need completely disjunct set of config variables.

I think we need to return to the dropped -DCAKE_PKG_UPDATE_NOW - triggered clone-or-update behavior

[URL [?branch=] | NAME ] [BRANCH ]

implies a CLONE
fetches (only if needed)
checks out named branch tag commit

see the removed implementation of cake_pkg CLONE (in an older commit) which handled updates

in accordance with ExternalProject

url, definitions and branch with '!' will be interpreted as mandatory, not meeting it would could FATAL_ERROR

example:

cake_pkg(INSTALL URL !http://github.com/a/b?!branch=devel&!-DFOO=BAR
DEFINITIONS !-DFOO=BAR
BRANCH !master
BRANCH !208394723984

implement the code to actually use the cake_name_url_db

cake_public_headers: add FILES and emphasize: no files after GLOB/GLOB_RECURSE

single library with dependencies and test
single exe with dependencies
super project with external and subdir dependencies

the current way ?depth=x should be removed
introduce
CAKE_PKG_CLONE_DEPTH
CAKE_PKG_CLONE_DEPTH_SUBDIR
CAKE_PKG_CLONE_DEPTH_EXTERN
variables which control the depth

• generate a report, just like git-repo's manifest which contains which repo is on which commit, which can mean the following things
• which is the original commit or branch this repo would be cloned by a fresh cmake configure (this is the branch parameter of the first encountered CLONE or INSTALL operation, the 'branch' field in the repo_db
• which branch or commit (if detached head) the repos are currently on
• exactly which commits the repos are currently on
  This should be saved to cmake file which can be later processed by another command, which:
• reads in the file
• restores the repos to the commit listed in the file

This file should be a

• a list of cakepkg CHECKOUT URL BRANCH commands
  (or alternatively
• a csv file or a more complicated format
• a list of cmake set(...) commands describing the situation
  )

This is required to do things like

list(APPEND CAKE_PKG_CAKE_ARGS -DCMAKE_MODULE_PATH=<...>)

and this would affect

cake_pkg(INSTALL NAME ZLIB)

which loads the cakecfg.cmake file but should keep CAKE_PKG_CAKE_ARGS as is because it must be passed on as session var

Extra care needed for arguments containing lists, like such lines in cakecfg:
-DCMAKE_INSTALL_PREFIX=path1;path2

implement the code that actually use cake_pkg_depends_db
