Hello, Have you try to add the header files in the add_library command to explicitely add a dependency over it ?
add_library(MyLib SHARED my_source.cpp ../MyHeaders/header.hpp etc.) On 10/21/19 4:16 PM, David Aldrich wrote: WARNING: External email, please be mindful before clicking or replying. Hi again, My CMakeLists.txt file for my shared library contains: add_library(MyLib SHARED my_source.cpp etc.) target_include_directories( MyLib PRIVATE ../MyHeaders) The library builds ok, but there is no dependency on directory ../MyHeaders - touching a header file does not result in a re-compile of dependent source files.
