[CMake] Why some libs use `CONFIGURE_DEPENDS`???

It causes creation of `...\CMakeFiles\VerifyGlobs.cmake` polluted with glob checks for certain boost libraries:

There is no need to re-check globs for 3rd party libs that are being changed only on pulling updates (not frequent change).
I believe `VerifyGlobs.cmake` should only contain user globs, if user specified `CONFIGURE_DEPENDS` in his own project.

Good alternative example is the `boost::beast` that uses glob only in non-library mode:
```cmake
if (BOOST_BEAST_IS_ROOT)
file(GLOB_RECURSE BOOST_BEAST_HEADERS CONFIGURE_DEPENDS include/boost/*.hpp)
set_property(GLOBAL PROPERTY USE_FOLDERS ON)
source_group(TREE ${CMAKE_CURRENT_SOURCE_DIR}/include/boost PREFIX "" FILES ${BOOST_BEAST_HEADERS})
target_sources(boost_beast PRIVATE ${BOOST_BEAST_HEADERS} build.jam)
endif ()
```
