File GLOB_RECURSE incorrectly filters directories

Code
1

I have the following dir [sub]structure:

├── src
│   ├── Mistery
│   │   ├── IntegrationTests
│   │   └── mistery.txt
│   ├── SomeFolder
│   │   └── AnotherFolder
│   └── UnitTests

And I try to find all directories which end with “Tests”. Here is a small cmake code for that:

file(GLOB_RECURSE TEST_FOLDERS LIST_DIRECTORIES true RELATIVE "${CMAKE_SOURCE_DIR}" src/*Tests)
message("Folders: ${TEST_FOLDERS}")

And here is the output:

Folders: src/Mistery;src/Mistery/IntegrationTests;src/SomeFolder;src/SomeFolder/AnotherFolder;src/UnitTests

As you can see instead of returning all the directories which end with “Tests” it just returned all the directories it found, the only thing it filtered out is the mistery.txt file. What am I doing wrong?
