Linking to a Windows shared library (.dll) requires only its import
library (.lib). This teaches CMake to recognize SHARED IMPORTED library
targets that set only IMPORTED_IMPLIB and not IMPORTED_LOCATION.
When an IMPORTED target provides no generic configuration and no match
for a desired configuration then we choose any available configuration.
This change corrects the choice when the first listed available
configuration does not really have a location.
Previously KWSys SystemInformation parsed this file assuming a strict
order and set of fields, but the order is not reliable. This
generalizes the implementation to support any order and extra fields.
The transitive link dependencies of a linked target must be followed in
its own scope, not in the scope of the original target that depends on
it. This is necessary since imported targets do not have global scope.
See issue #8843.
The previous wording of the VERBATIM option documentation in the
add_custom_command and add_custom_target commands was confusing. It
could be interpreted as the opposite of what the option means (no
escaping instead of escaping). This clarifies the documentation to
explicitly state that it escapes.
The value of CMAKE_CURRENT_LIST_FILE is supposed to be the list file
currently being executed. Before macros were introduced this was always
the context of the argument referencing the variable.
Our original implementation of macros replaced the context of command
arguments inside the macro with that of the arguments of the calling
context. This worked recursively, but only worked when macros had at
least one argument. Furthermore, it caused parsing errors of the
arguments to report the wrong location (calling context instead of line
with error).
The commit "Improve context for errors in macros" fixed the latter bug
by keeping the lexical context of command arguments in macros. It broke
evaluation of CMAKE_CURRENT_LIST_FILE because the calling context was no
longer preserved in the argument referencing the variable. However,
since our list file processing now maintains the proper value of
CMAKE_CURRENT_LIST_FILE with dynamic scope we no longer need the context
of the argument and can just evaluate the variable normally.
The add_definitions() command and COMPILE_DEFINITIONS dir/tgt/src
properties support preprocessor definitions with values. Previously
values were not supported in the VS6 generator even though the native
tool supports them. It is only values with spaces that VS6 does not
support. This enables support and instead complains only for values
with spaces. See issue #8779.
