The changes in commit 47b060ae (CPackDeb: allow empty directories in
component packages, 2015-09-21), commit b58de9fe (CPack: allow packaging
of empty directories, 2015-09-21), and commit b761e90d (CPack: remove
accidental changes, 2015-09-22) regressed packaging of CMake itself.
Revert the changes until they can be revised and rebased on other
changes that make additional fixes.
This setting was added to support QtIFW 2.0 in commit v3.3.0-rc1~70^2~1
(CPackIFW: Add QtIFW 2.0 support, 2015-04-27). We need to load the
CPackIFW module to initialize it if it is not set.
fa9eb814 cmLocalGenerator: Remove redundant path access.
1933f3d1 cmLocalGenerator: Remove redundant path conversions.
9e4b6cc2 cmState: Store computed relative paths to to current directories.
991f5e49 cmState::Snapshot: Store components for current directories.
57bdc1a2 cmState: Compute and store directory components.
There is no need to duplicate these in all cmLocalGenerators.
Rename the symbols according to current conventions.
Add explicit calls to Set{Source,Binary}Directory with empty strings
in order to trigger the population of the components containers with
the current working directory in cmLocalGenerator. Having
directories set to empty is a special case in CMake, which is relied
on for the `if(CMAKE_BINARY_DIR)` condition at the end of
CMakeDetermineSystem.cmake.
Preparation for per component variables.
Patch makes sure we know which variables
will be set for per component generator
and also prevents accidental overflows
of variable values between components.
Extend the RunSingleCommand signature to capture stdout and stderr
separately. Allow both to be captured to the same std::string
to preserve existing behavior. Update all call sites to do this
so that this refactoring does not introduce functional changes.
This is a unique function call in CMake, and it was likely a
programming error when introduced. All other similar calls to
ReadListFile use a null first paramter.
The effect of this patch is to no-longer define CMAKE_PARENT_LIST_FILE
to the config file itself while evaluating it.
The ReadListFile method also no longer hits a condition that it uses
CollapseFullPath on the input file. However, as cpack does not
set the StartDirectory anyway, this has no effect. See bug 15522.
Refine logic added in commit 0ffd3534 (CPack single component packaging,
2015-04-02). Component packaging should be enabled if either at least
one component or one group is set and should not require both.
RPM, DEB and archive packages were not created
in cases when CPACK_<generator>_COMPONENT_INSTALL
was set to ON and a single component existed.
Patch also changes CPackRPM test to implicitly
test for this case.
In cpack we load the platform information modules to give the
configuration scripts access to the host system information.
CYGWIN.cmake warns unless we explicitly tell it not to warn
since there is no chance for a cmake_minimum_required(VERSION)
to be called.
The CMAKE_MAKE_PROGRAM selected by CMake while configuring the project
should also be used to drive the "preinstall" target during packaging.
Teach CPack to use "cmake --build" instead of constructing the build
command line itself. The "cmake --build" command already knows how
to select the proper make tool.
