Recently we taught find_package to re-find a package if its
<package>_DIR result variable was set to a location not containing the
package (instead of reporting an error as before). This tests the
feature.
The new 'testing' test behavior of actually running the tests generated
by the project still fails when the test script guesses the Debug
configuration but the CMake build tree was only built Release. The
inner ctest needs to find the ctest executable but is given the wrong
configuration.
The recent change of the 'testing' test to actually drive the tests
within it does not work on Windows with released CMakes 2.6.2 and lower
if no configuration is given to ctest with a -C option. This works
around the problem by detecting the case and changing the empty
configuration to Debug.
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.
The 'testing' CMake test builds a project that uses add_test. This
strengthens the test to actually run CTest on the project build tree
after building it.
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.
The previous change to test finding in lib/cmake/<name>* weakened the
versioned find tests. Since the lib/cmake paths are searched before
lib/<name>* paths the previous change skipped requiring the command to
ignore zot-3.0 when finding zot-3.1. This change restores that and adds
zot-4.0 to test the lib/cmake path.
This teaches find_package to search
<prefix>/(share|lib)/cmake/<name>*/
for package configuration files. Packages that do not already have
files in a <prefix>/lib/<name>* directory can use this location to avoid
cluttering the lib directory.
When CMake is built by CMake 2.4 or lower the FindCVS module is not
available. In that case we activiate CTest.UpdateCVS by searching for
the cvs command directly.
This creates new tests "CTest.UpdateSVN" and "CTest.UpdateCVS". They
test that the Update.xml produced by CTest for a version-controlled
project contains entries for files added, changed, and removed.
