The add_external_project function separates its arguments with ';'
separators, so previously no command line argument could contain one.
When specifying CMAKE_ARGS, some -D argument values may need to contain
a semicolon to form lists in the external project cache.
This adds add_external_project argument LIST_SEPARATOR to specify a list
separator string. The separator is replaced by ';' in arguments to any
command created to drive the external project. For example:
add_external_project(...
LIST_SEPARATOR ::
CMAKE_ARGS -DSOME_LIST:STRING=A::B::C
...)
passes "-DSOME_LIST:STRING=A;B;C" to CMake for the external project.
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.
CVS clients recognize file modifications only if a file's timestamp is
newer than its CVS/Entries line. This fixes intermittent failure of the
test on filesystems with low timestamp resolution by delaying before
creating a local modification.
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.
This fixes the get_configure_command_id function to not mistake
CONFIGURE_COMMAND values that run "cmake -P" or "cmake -E" for a CMake
project configuration. These values just help run scripts.
This creates function 'add_external_project_step' to centralize creation
of external project steps. Users may call it to add custom steps to
external project builds.
The add_external_project function parses its arguments and puts them in
properties of the target it creates. This factors out implementation of
the behavior for use by other functions in the module.
