I tried to solve that inconsistency for NON_TRANSITIVE ON for the static library case with FORCE_EXTERNAL_STATIC ON, but (see other thread about FORCE_EXTERNAL_STATIC) that did not work out because of deficiencies in the static library support for Linux. I was able to resolve the inconsistency by installing one additional development package on Debian stable (libjasper-dev), but the fact remains that such inconsistencies will always be a threat for the (internal) static library case and NON_TRANSITIVE ON. So I fundamentally solved the issue (revision 12066) by only allowing NON_TRANSITIVE ON for the shared libraries case. After all, from the perspective of CMake, NON_TRANSITIVE ON is a no-op for the static library case which is why pkg-config was out of step. This solves the issue by forcing pkg-config to be in step with what happens for cmake (i.e., NON_TRANSITIVE ON is ignored for the static case). I also did one additional change (revision 12067) which is deletion of our versions of FindwxWidgets.cmake and FindwxWidgets.cmake. That is no longer necessary or desireable for the reasons I stated in the commit message. I took this opportunity to do a complete comprehensive test (all 21 major tests) not only of this change, but everything that has happened recently with regard to NON_TRANSITIVE ON. This comprehensive test passed with flying colours with no build errors or obvious run-time errors for any of the 21 different tests. So this should complete my NON_TRANSITIVE changes to the build system. Orion and Andrew: I hope this effort has been worth it and greatly reduces packaging warnings you have been getting on both Fedora and Debian concerning overlinking.
