Every CPack generator sets default CPACK_PACKAGING_INSTALL_PREFIX
variable value differently so test framework should support
that correctly - previous version expected RPM/Deb /usr default and
removed it for Archive packagers as the default there is /.
Adds support for epoch version to CPackRPM and
CPackDeb packagers.
Also adds better version checking to CPackDeb
that complies with Debian rules.
Fixes: #17057
Prerequirements should be searched for in
generator prerequirements function and only
checked for presence in configure file in
per test prerequirements function.
CPack tests can now define one or more
packaging types and that test will be
executed once per generator per packaging
type. This also enables us to set default
values per packaging type for each generator
which makes tests shorter.
Content list for a certain test
should be the same between different
generators so whenever possible use
a single expected files list per
file for all generators.
Each generator generates its own file
format with different extensions but
they all create those file names by
a certain pattern and all of them
require the same pieces for that pattern
to work. Now we can only provide pieces
once and and each generator will use those
pieces to generate an expected file name.
Package names are irrelevant for most
CPack tests so tests now set default
package name that is created from test
name and used if it is not explicitly
provided in the test.
This patch preserves backward compatibility of
deb package names with previous CMake versions
but similarly to CPack/RPM allows to change
package name format and supports DEB-DEFAULT
setting that produces proper Debian package names.
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.
