These new capabilities enable to manage link directories
Two new properties:
* target properties: LINK_DIRECTORIES and INTERFACE_LINK_DIRECTORIES
One new command
* target_link_directories(): to populate target properties
Fixes: #17215
This family enable to manage link flags
Three new properties:
* directory property: LINK_OPTIONS
* target properties: LINK_OPTIONS and INTERFACE_LINK_OPTIONS
Two new commands
* add_link_options(): to populate directory property
* target_link_options(): to populate target properties
Fixes: #16543
The purpose of this new `IMPORTED_GLOBAL` target-property is to prolong
the lifetime and scope of `IMPORTED` targets in such a way as if they
had been created with the keyword `GLOBAL` in the first place.
* It can only be set to `TRUE`. That means, a local `IMPORTED` target
can be promoted to global scope but a global `IMPORTED` target cannot
be degraded to local scope!
* Setting it to `TRUE` only succeeds if done from within the same
directory in which the `IMPORTED` target was created in the first
place.
Fixes#17256.
Extend the RunCMake.set_property test with cases covering buildsystem
directory properties:
* COMPILE_DEFINITIONS
* COMPILE_OPTIONS
* INCLUDE_DIRECTORIES
Also test a non-buildsystem property to document the equivalence
in behavior.
This is a change in behavior from CMake 3.3, but there is no semantic meaning
to empty entries in buildsystem properties. This also restores behavior to
that of CMake 2.8.10.
Extend the RunCMake.set_property test with cases covering buildsystem
target properties:
* COMPILE_DEFINITIONS
* COMPILE_FEATURES
* COMPILE_OPTIONS
* INCLUDE_DIRECTORIES
* LINK_LIBRARIES
* SOURCES
Also test a non-buildsystem property to document the current difference
in behavior. Refactor the existing LINK_LIBRARIES case to the same
more-extensive test as the rest. Use the output generated by CMake 3.3
as the expected output for each test case.
The test case added to RunCMake.set_property by commit 675ef165 (Allow
LINK_SEARCH_{START,END}_STATIC props to have default values, 2015-08-07)
is not a test of the set_property command and so belongs in its own test
case. Create a new RunCMake.LinkStatic test to cover cases related to
static linking.
While at it, simplify the LINK_SEARCH_STATIC test case to enable only C.
Use the CMAKE_LINK_SEARCH_START_STATIC and CMAKE_LINK_SEARCH_END_STATIC
variables to initialize the LINK_SEARCH_START_STATIC and
LINK_SEARCH_END_STATIC target properties respectively.
We use a special dedicated structure to store the LINK_LIBRARIES target
property. Do not try to construct a string from a NULL value. Instead
leave the property structure empty when no value is given.
