You'll need to export CMAKE_MODULE_PATH with: set(CMAKE_MODULE_PATH "${CMAKE_MODULE_PATH};<new_path_here>" PARENT_SCOPE) which will set it in the calling scope or possibly set_property( GLOBAL .... ) although I'm not sure that would work. I've never done this from inside a function - instead I've always set this at the top-level CMakeLists.txt within an include file: include(cmake/module_paths.txt NO_POLICY_SCOPE) And in cmake/module_paths.txt use something like: ... use an include guard here (omitted) ... list( APPEND CMAKE_MODULE_PATH "$(CMAKE_CURRENT_LIST_DIR}/my_modules" ) The NO_POLICY_SCOPE on the include prevents the need for using set( ... PARENT_SCOPE) which will fail if this is the top scope. > > Is this a bug? Or is there something different I need to do? > > regards > > Fabio > > -- > Dipl.-Inf.
