Using GLOB is slow and considered bad practice. From https://cmake.org/cmake/help/latest/command/file.html: > We do not recommend using GLOB to collect a list of source files from > your source tree. If no CMakeLists.txt file changes when a source is > added or removed then the generated build system cannot know when to ask > CMake to regenerate. The CONFIGURE_DEPENDS flag may not work reliably on > all generators, or if a new generator is added in the future that cannot > support it, projects using it will be stuck. Even if CONFIGURE_DEPENDS > works reliably, there is still a cost to perform the check on every > rebuild.
