[SOLVED] Looping over files matching wildcard in CMake

Issue

I want to use CMake to run some tests. One of the test should call a validator script on all files matching fixtures/*.ext. How can transform the following pseudo-CMake into real CMake?

i=0
for file in fixtures/*.ext; do
  ADD_TEST(validate_${i}, "validator", $file)
  let "i=i+1"
done

Solution

Like this:

file(GLOB files "fixtures/*.ext")
foreach(file ${files})
  ... calculate ${i} to get the test name
  add_test(validate_${i}, "validator", ${file})
endforeach()

But this does not calculate i for you. Is it important that you have an integer suffix to the test? Otherwise you could use file(...) to extract the filename (without extension) to use.
