cmake: fix build with ninja instead of make
cmake: fix build with ninja instead of make

cmake does not actually support glob expressions inside DEPENDS of
custom commands. However make, because it runs every command inside
a shell, can make sense of these expressions, but other build system
generator like ninja won't. Replacing the glob expressions by an
explicit file glob in cmake fixes that.
