That should trigger a regeneration of these swig sources if any of the header files change. This is done via a small macro that can be reused for other wrappers as well. Note cmake 3.15 introduces a 'FILTER' generator expression that might allow us to do something like the following: $<FILTER:$<TARGET_PROPERTY:baselib,SOURCES>,INCLUDE,"*.h[pp]?$"> I toyed briefly with that idea but it currently has two issues: 1. 3.15 is newer than our current minimum cmake requirement, so we can't depend in that feature yet. 2. the sources are relative to *their* source directory, which is different from the one in which the wrappers are generated So they should still be properly transformed into absolute paths
