ToDo: We need to check that the SOURCES var is empty if HEADERONLY is passed in. Current, we just ignore SOURCES. Signed-off-by: Roscoe A. Bartlett <[email protected]>
…iBITSPub#625) This failing test shows that an INTERFACE library was not getting picked up and linked to the <Package>::all_libs target. The reason the existing tests all passed after adding the initial support for HEAERONLY INTERFACE libraries was that I added the interface library 'mixedlang_vector' before the main 'mixedlang' library. So the new 'mixedlang_vector' library is getting written to the MixedLangTargets.cmake file and is getting linked to 'mixedlang' and 'mixedlang' was getting liked to MixedLang::all_libs. So, anyone that was linking against MixedLang::all_libs or just the 'mixedlang' LIB (from internal or IMPORTED target) was getting the include directories being specified in the 'mixedlang_vector' library. But this implementation fails for TriBITS packages that only have INTERFACE libraries. Those are never getting added to the <Package>::all_libs target or indirectly to targets that do. This is why the STKEmend package failed because it has just one HEADERONLY INTERFACE library. This new added test case ensures that the INTERFACE library does get linked to the <Package>::all_libs target and will fail if it does not. The next commit will add the code in TriBITS to fix this test :-) Signed-off-by: Roscoe A. Bartlett <[email protected]>
…ub#625) This fixes the previously added failing test :-) I also had to add logic to not generate the package-config files when doing installation testing where you are only building the tests and examples. This was generating a strange error about export sets. You should not be generating packge-config files in these cases. Also, this change required the update of some other tests. Now that INTERFACE_LIBRARY taragets are getting pulled down, the <SubPkg>::all_libs for subpackage targets are getting added the <ParentPkg>::all_libs target for parent packages. This is an intereting case but it works. Signed-off-by: Roscoe A. Bartlett <[email protected]>
