* Convert CMake to OSI-approved BSD LicenseBrad King2009-09-281-14/+9
| | | | | | | 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.
* Create GLOBAL_DEPENDS_NO_CYCLES propertyBrad King2009-08-241-0/+1
| | | | | This global property disallows cycles in the inter-target dependency graph even among STATIC libraries. See issue #9444.
* BUG: Avoid bogus dependency on executable targetsBrad King2008-08-061-1/+2
| | | | | | | | | | | | When an executable target within the project is named in target_link_libraries for another target, but the executable does not have the ENABLE_EXPORTS property set, then the executable cannot really be linked. This is probably a case where the user intends to link to a third-party library that happens to have the same name as an executable target in the project (or else will get an error at build time). We need to avoid making the other target depend on the executable target incorrectly, since the executable may actually want to link to that target and this is not a circular depenency.
* ENH: Improve link line generation for static library cycles.Brad King2008-02-071-28/+14
| | | | | | | | | - Move Tarjan algorithm from cmComputeTargetDepends into its own class cmComputeComponentGraph - Use cmComputeComponentGraph to identify the component DAG of link dependencies in cmComputeLinkDepends - Emit non-trivial component members more than once but always in a contiguous group on the link line
* ENH: Analyze inter-target dependencies to safely fix cyclesBrad King2008-02-061-0/+90
- Cycles may be formed among static libraries - Native build system should not have cycles in target deps - Create cmComputeTargetDepends to analyze dependencies - Identify conneced components and use them to fix deps - Diagnose cycles containing non-STATIC targets - Add debug mode property GLOBAL_DEPENDS_DEBUG_MODE - Use results in cmGlobalGenerator as target direct depends
