ninja-clean-failure

CMake project that illustrates the build | clean failure with Ninja on Windows

Includes a dependency to libwebsockets which causes a nested directory within the libwebsockets-build directory that ninja is unable to remove on clean.

Note* libwebsockets typically requires OpenSSL (or some SSL library) so you may need to install through chocolatey

Steps to reproduce:

1. Open project in CLion
2. Select Build | Build Project
3. Select Build | Clean

Expected:

• clean is successful

Actual: Error in Build output window similar to,
