This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
This introduces a new syntax called "generator expressions" to the test
COMMAND option of the add_test(NAME) command mode. These expressions
have a syntax like $<TARGET_FILE:mytarget> and are evaluated during
build system generation. This syntax allows per-configuration target
output files to be referenced in test commands and arguments.
We teach cmTestGenerator::GenerateScriptConfigs to use the general
cmLocalGenerator::EscapeForCMake method to write escaped test property
values into test scripts. This eliminates the previous hand-coded
escaping implementation.
This creates command mode add_test(NAME ...). This signature is
extensible with more keyword arguments later. The main purpose is to
enable automatic replacement of target names with built target file
locations. A side effect of this feature is support for tests that only
run under specific configurations.
This moves code which generates ADD_TEST and SET_TESTS_PROPERTIES calls
into CTestTestfile.cmake files out of cmLocalGenerator and into a
cmTestGenerator class. This will allow more advanced generation without
cluttering cmLocalGenerator. The cmTestGenerator class derives from
cmScriptGenerator to get support for per-configuration script
generation (not yet enabled).
