CMake has a builtin dependency checker for supported language (C, C++,
Fortran, ...)
so yes it should work.

Did you try ? Do you have a counter-example?

That said specifying all files (including headers) in your CMakeLists.txt
may be a good habit too.

Have a look at:

PUBLIC_HEADER, PRIVATE_HEADER, HEADER_FILE_ONLY CMake properties.
cmake --help-property PUBLIC_HEADER

and the PUBLIC_HEADER option of the INSTALL(TARGETS) command.

you'll see that explicitely specifying headers in CMakeLists.txt may be useful.
