Rolf Eike Beer	ec631d5043	add a test that loops through most Find* modules ... This allows easy spotting of modules that output crappy messages and the like.	2012-01-16 23:37:13 +01:00

Rolf Eike Beer	8e1f376782	add a test for Check{,CXX}SymbolExists ... Now that we think that CheckSymbolExists really works for all cases it is time to prove that. If this code fails too many other things will break.	2012-01-16 20:52:29 +01:00
Brad King	8e756d2b9b	Tolerate cycles in shared library link interfaces (#12647) ... Since commit 183b9509 (Follow all dependencies of shared library private dependencies, 2011-12-14) we honor LINK_INTERFACE_LIBRARIES when following dependent shared libraries. The link interface properties may form a cycle if set incorrectly by a project. Furthermore, the property LINK_DEPENDENT_LIBRARIES may form a cycle if set incorrectly by hand (though CMake should never generate one). In either case, do not follow the cycle forever when following the dependent shared library closure. We only need to add dependency edges to the constraint graph once. Add "LinkInterfaceLoop" test to cover this case.	2012-01-13 14:22:24 -05:00
Brad King	9a20abf04a	Add infrastructure for CMake-only tests ... Some tests only need to run CMake to configure and generate a build tree, but not actually perform the build. Add a new "Tests/CMakeOnly" directory dedicated for this purpose. Add a helper script to drive each test by creating a fresh build tree and running CMake on it. Add macro "add_CMakeOnly_test" to help create tests using the script.	2012-01-13 14:21:22 -05:00
