Other Notes/Information

Clicking “Quickstart a new CMake project” fails with the message: “This workspace already contains a CMakeLists.txt!”

I’m guessing this has to do with the fact that Windows uses case insensitive file paths.

[Quincunx271]

Here’s what happened: I created the directory from the Windows Subsystem for Linux (WSL), even though it is a Windows folder. Windows automatically enables case sensitivity for files created from the WSL, meaning that the paths are actually case sensitive.

I verified it by running fsutil.exe:

C:\...\pitchfork>fsutil.exe file queryCaseSensitiveInfo .
Case sensitive attribute on C:\...\pitchfork is enabled.

[marc-h38]

I have no idea how to fix this but in the meantime a small error message change would really go a long way and save a number of lives. Something like:

  The source directory
    C:\Users\joe\Project\foo\bar\
  does not contain a CMakeLists.txt file. Note Windows supports per-directory case-sensitivity. We're not joking.
