CMAKE_xxx vars are now used in the CMake-generated cmake_install.cmake
script while CPACK_xxx equivalent vars are used from within CPack.
CPack is responsible for getting/forwarding definitions of
CPACK_xxxx var corresponding to CMAKE_xxxx when invoking
CMake-generated install scripts.
As a consequence:
CMAKE_ABSOLUTE_DESTINATION_FILES
CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION
CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION
may be used from outside CPack as well.
e.g.
cmake -DCMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION=1 -P cmake_install.cmake
works as expected.
The [usually] wrong usage of absolute DESTINATION in INSTALL rules
keeps popping-up on the ML. We shall have some way to:
1) easily detect it.
2) forbids this for some CPack generator like NSIS
In fact it should certainly be forbidden for *any* generators
when used on Windows but we may implements that on top of the current
patch.
The patch ask the task to the generated cmake_install.cmake scripts.
Those scripts are a little bit more complicated with that but
iff there are absolute DESTINATION. This cost nothing if relative
DESTINATION are used.
Two new vars are introduced (and documented to handle that):
CPACK_WARN_ON_ABSOLUTE_INSTALL_DESTINATION
and
CPACK_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION
This concerns all variables common to all CPack generators.
Variables mainly used and/or set in CPack.cmake are documented
therein. C++ built-in variables are documented in
cmCPackDocumentVariables.cxx.
- Enhance extract doc parser. Seems robust now. The legacy
module documentation parser works as before ignoring
the new markup.
- Proof of concept for CPack (generic), CPack RPM and CPack Deb
generator for macro and variables.
Try cpack --help-command and cpack --help-variables
The language is very simple. It use ##<keyword> special comment
which opens a structured documentation block and ##end closes it.
This may be used to extract documentation for macro as 'command'
and 'variables' such that cpack --help-command and --help-variable
does parse builtin modules files (CPack.cmake, CPackComponent.cmake,
...) in order to extract the corresponding doc.
This modifications set tries to keep the unified doc for cmake/ctest/cpack
while introducing tool specific documentation separated.
Some documentation sections for CMake do not fit well to CPack.
