When CMake 2.4 generates the build tree for CMake itself it asks the
built CMake to install itself using the rules that 2.4 generated. Since
the install rules use undocumented commands that are not compatible from
2.4 to 2.6 we need a special case to avoid failure. This sets a special
indicator variable in the install rules that enables a compatibility
hack to support the old install rule format.
The internal file(INSTALL) command argument parsing used several
booleans with at most one set to true at a time to track argument
parsing state. This refactors it to use one enumeration.
The get_target_property command contained some outdated documentation of
the LOCATION and TYPE properties. This removes it since they are now
documented in the properties list section of the documentation.
Previously we left the LOCATION property undefined for imported targets
since it should no longer be used for non-imported targets. However, in
the case we do not know the name of an available imported configuration,
it is more readable to get the LOCATION property than LOCATION_<CONFIG>
for a bogus configuration <CONFIG>. This enables LOCATION for imported
targets and returns an unspecified available imported configuration.
The FATAL_ERROR to cmake_minimum_required is useful for projects that
require 2.6 to convince CMake 2.4 to error out. This clarifies its
usefulness in the documentation.
When cmake_minimum_required is called with an unknown argument it should
not complain about it if the version specified is in the future. This
allows the proper error to be shown about the current CMake being too
old.
When computing runtime search path ordering a constraint exists when a
file that may be found by the runtime search exists in a directory other
than that containing the desired file. We test whether a potential
conflict is really the same due to a symlink. Recently the change to
cmFindLibraryCommand to load directory content created a case in which
the same-file check would be incorrectly skipped. This avoids skipping
the check.
On Windows the KWSys System package generates escapes for command-line
arguments. This fix enables quoting of the empty string as an argument.
This also adds a test to pass an empty argument to a custom command.
When ctest --build-and-test runs the --test-command its output did not
quote the arguments of the command being tested making it difficult to
read. This adds the quotes. This also changes the wording of the
failure case to not sound like CTest could not run the executable when
in fact it ran and returned failure.
When CTest encounters a test whose executable is the ctest executable
iteslf, it just invokes code inside itself to avoid starting a new
process. This fixes a null-pointer dereference in the logging code of
that case.
The command argument lexer was recently regenerated which erased some
fixes that had been applied directly to the output. This restores the
fixes and adds reminder notes in the generation instructions.
The command argument parser code is generated by bison. This change
restores some fixes previously applied to the generated output that were
destroyed by regenerating the parser source. This time the fixes have
been put in the input file so regenerating the parser will not destroy
them again.
We now search in
<prefix>/<name>*/
<prefix>/<name>*/(cmake|CMake)
when looking for package configuration files. This is useful on Windows
since the Program Files folder is in CMAKE_SYSTEM_PREFIX_PATH. These
paths are the Windows equivalent to the Apple convention application and
framework paths we already search. See issue #8264.
The $ENV{VAR} syntax permits access to environment variables. This
teaches CMake to recognize most characters in the VAR name since some
environments may have variables with non-C-identifier characters.
For bug #7191.
Improvements to the dialog that sets up the first configure.
Fixing the large size of it by breaking it up into a wizard.
Also incorporated suggestions from bug report.
When the find_package command loads a <name>-version.cmake file to test
the package version it must prevent the version file from affecting
policy settings. Therefore the policy settings must be pushed and
popped.
