| * cmTarget: Fix diagnostic of target_link_libraries in wrong directory (#15626)Brad King2015-06-251-1/+2
| | | | | | | | | | | | | | | | | | | | Since commit v3.3.0-rc1~62^2~5 (cmTarget: Store only cmListFileContext for CMP0023 handling, 2015-05-18) a call to target_link_libraries on a target that was defined in another (non-ancestor) directory crashes because no execution context is left active. Fix this by getting the execution context from the actual cmMakefile where the current target_link_libraries call takes place. Test this by verifying that such calls correctly produce an error diagnostic instead of crashing.

* Honor visibility properties for all target types (#15556)Brad King2015-05-261-1/+2
| | | | | | | | | | | | | | | | The <LANG>_VISIBILITY_PRESET and VISIBILITY_INLINES_HIDDEN were first merged in commit v2.8.12~322 (Merge topic 'VISIBILITY_PRESET-property', 2013-06-05) but worked only for shared libraries and executables with exports. Prior to commit v3.0.0-rc1~581^2 (GenerateExportHeader: Deprecate add_compiler_export_flags function., 2013-09-02) the add_compiler_export_flags function was used to add visibility flags to all targets. The visibility flags are useful for sources in all target types because they may be later linked into shared libraries or executables with exports. Introduce policy CMP0063 to enable them for all target types while preserving compatibility with existing projects that do not expect this.

* Link libraries by full path even in implicit directoriesBrad King2015-04-091-1/+2
| | | | | | | | | | | | | | | | | | | | | | When CMP0003 was first introduced we wanted to link all libraries by full path. However, some projects had problems on platforms where find_library would find /usr/lib/libfoo.so when the project really wanted to link to /usr/lib/<arch>/libfoo.so and had been working by accident because pre-CMP0003 behavior used -lfoo to link. We first tried to address that in commit v2.6.0~440 (Teach find_library to avoid returning library paths in system directories, 2008-01-23) by returning just "foo" for libraries in implicit link directories. This caused problems for projects expecting find_library to always return a full path. We ended up using the solution in commit v2.6.0~366 (... switch library paths found in implicit link directories to use -l, 2008-01-31). However, the special case for libraries in implicit link directories has also proven problematic and confusing. Introduce policy CMP0060 to switch to linking all libraries by full path even if they are in implicit link directories. Explain in the policy documentation the factors that led to the original approach and now to this approach.

* | cmTarget: Cache compatible interface property setsBrad King2014-07-161-0/+10
| | | | | | | | | | | | | | Replace isLinkDependentProperty with a CompatibleInterfaces structure that records all the compatible interface properties in a set for each type. This avoids repeatedly traversing the link implementation closure and asking every target for its compatible interface properties.

* | cmTarget: Rename old-style link dependencies code as "ForVS6"Brad King2014-07-141-19/+19
|/ | | | | | The old link dependency analysis is now needed only for the VS 6 generator code delimited by CM_USE_OLD_VS6 to support project-provided project templates. Rename the related cmTarget members to be "ForVS6".
* cmTarget: Add to LinkImplementation whether each library was a genexBrad King2014-07-071-4/+6
| | | | | | Implementation of CMP0027 OLD behavior needs to know whether each entry in LinkImplementation::Libraries came from a generator expression or not. Add a FromGenex member to cmLinkImplItem to record this.

* cmTarget: Refactor LinkImplementation to allow more informationBrad King2014-07-071-1/+11
| | | | | | | Create a cmLinkImplItem class derived from cmLinkItem so more information can be added to link implementation entries than link interface entries. Convert the LinkImplementation Libraries member to hold it. Update client sites accordingly.
* cmTarget: Teach GetLinkInterfaceLibraries to support $<LINK_ONLY>Brad King2014-06-251-3/+5
| | | | | | | Add a 'usage_requirements_only' parameter to GetLinkInterfaceLibraries and supporting internal APIs to pass through to ExpandLinkItems so it knows whether to use SetTransitivePropertiesOnly while evaluating generator expressions.
* cmTarget: Teach ExpandLinkItems how to support $<LINK_ONLY>Brad King2014-06-251-0/+1
| | | | | | | Add a 'usage_requirements_only' parameter to ExpandLinkItems so that it knows whether to use SetTransitivePropertiesOnly while evaluating generator expressions. Update existing call sites to pass 'false' since they are for linking and not usage requirements.
* cmTarget: Drop GetDirectLinkLibraries methodsBrad King2014-06-231-5/+0
| | | | | Inline the implementation in the last remaining caller and drop the methods.
* cmTarget: Lookup targets in LinkInterface and LinkImplementationBrad King2014-06-231-6/+8
| | | | | | | | | | | | | | | Instead of storing just the string names in these structures, lookup any target associated with each item and store its cmTarget pointer. Use the cmLinkItem class to hold the name and pointer together. Update client sites to use the pre-stored lookup result instead of looking up the target name again. Create a cmTarget::LookupLinkItems helper method to handle the lookup. Since lookups are now moving from cmComputeLinkDepends::AddLinkEntries to cmTarget::LookupLinkItems, move use of CheckCMP0004 to the latter. This drops use of CheckCMP0004 from entries added for _LIB_DEPENDS variables by cmComputeLinkDepends::AddVarLinkEntries, but I do not think that use was intentional originally anyway.
* cmTarget: Add GetUtilityItems to get target ordering dependenciesBrad King2014-06-231-0/+1
| | | | | | | Add a method like GetUtilities but that provides the target names already looked up and resolved to cmTarget pointers internally. Update call site in cmComputeTargetDepends::AddTargetDepend to use the already-found target instead of looking it up again.
* cmTarget: Add cmLinkItem to refer to a target by name and pointerBrad King2014-06-231-0/+12
| | | | | | | | Many items named in target_link_libraries calls are targets, but not all. Create a cmLinkItem type that acts like std::string so it can name an item but also has a pointer to a cmTarget that is the result of looking up the item name in the referencing target's scope. This will be useful to avoid duplicate lookup operations later.
* cmTarget: Add method to lookup other targets in a target's scopeBrad King2014-06-231-0/+2
| | | | | Move the main implementation of cmComputeLinkDepends::FindTargetToLink into cmTarget.
* cmTarget: Constify GetLinkImplementationClosure resultsBrad King2014-06-231-1/+1

* cmTarget: Constify GetTransitivePropertyTargets resultsBrad King2014-06-231-2/+2
| | | | Populate a vector of "cmTarget const*" instead of "cmTarget*".
* cmTarget: Drop 'head' target from GetImportInfoBrad King2014-06-231-4/+7
| | | | | | | Move generator expression evaluation for imported library lists out of GetImportInfo and into a new GetImportLinkInterface helper. This avoids duplicating the computation and storage of all imported target info just because some of it is parameterized on the 'head' target.
* cmTarget: Remove 'head' argument from GetLinkImplementationBrad King2014-06-231-7/+11
| | | | | | | | | | | | | Many of the 'head' arguments added by commit v2.8.11~289^2~1 (Make linking APIs aware of 'head' target, 2013-01-04) turned out not to be needed. The "link implementation" of a target never needs to be computed with anything but itself as the 'head' target (except for CMP0022 OLD behavior because then it is the link interface). Remove the unused 'head' target paths. Add "internal" versions of cmTarget::GetDirectLinkLibraries and GetLinkImplementationLibraries to support the CMP0022 OLD behavior without otherwise exposing the 'head' target option of these methods.
