I stand corrected. If I completely remove the export of the Deps.cmake file, the build fails because of transient calls in cmake Macros/Function. For example project A calls macroB() defined in project B, while macroB() further calls macroC() defined in project C. So if BConfig.cmake (which is included by A) does not contain find_package(C) (which it would if exporting Deps.cmake which contains that call), building A fails, because macroC() is not defined, as no one calls find_package(C)- > > > Aleksandar > > >> Alex > > >
