(I still want to ensure that the folder is empty before removing it,
but
I don't know how to check if a directory is empty, suggestions?)
Forgot about this in my other reply.... You can check if a directory is
empty by doing a quick file(GLOB on it and counting the number of
results.
This code, saved as a *.cmake script, and then run with -P in various
directories:
set(dir ".")
file(GLOB r1 "${dir}/*")
list(LENGTH r1 n1)
message("n1='${n1}'")
file(GLOB r2 "${dir}/*.*")
list(LENGTH r2 n2)
message("n2='${n2}'")
convinces me that n1 and n2 should both be 0 in an empty directory, and
non-0 in a directory that contains any subdirs or files, even invisible
ones like .git.
HTH,
David
