Hi, Short notice: the EXCLUDE_FROM_ALL behaviour changed in CMake >= 3.14.0 when used with add_subdirectories().
EXCLUDE_FROM_ALL now also affects all the targets inside the directory.[1][2] e.g: add_subdirectory(foo EXCLUDE_FROM_ALL) Before: Targets defined in this directory are not built when running 'make' but can be built using 'make -C foo'. After: 'make -C foo' will not build anything. Projects concerned by this change: - kdev-pg-qt, 'make -C examples' does nothing with CMake 3.14 - kooka, 'make -C tools' won't build them [1] https://cmake.org/cmake/help/v3.14/prop_tgt/EXCLUDE_FROM_ALL.html? highlight=exclude_from_all [2] https://cmake.org/cmake/help/v3.14/command/add_subdirectory.html? highlight=add_subdirectory
