They don't actually have to be in one directory. You only need to name
them from one directory. For example:
add_executable(myMain
exe/mymain.f90
lib1/lib1.f90
lib2/lib2.f90
lib3/lib3.f90
)

If you want to build more than one executable that shares the same
libraries then it is better to build the individual libraries and
link to them from each executable. Otherwise each source file will
compile separately for each executable. In C this is just slower, but
in Fortran the .mod files might conflict. If you're building exactly
one executable then the approach has no significant drawbacks, at
least of which I can think now.
