run-vcpkg and run-cmake in github actions: The system cannot find the path specified on windows only

I try to make a new setup using github actions with CMake and vcpkg. All the configurations are working except the windows one. A strange error occurs and I'm not sure why it happens and I'm not sure how to fix it:

► Run lukka/run-cmake@v3

tool: D:\a\_temp\909795809\ninja.exe
► Setup environment variables for triplet 'x64-windows' using 'vcpkg env'

My workflow file is the following:

I mostly followed the run-vcpkg quickstart guide.

Solution

  • The problem has been reported here and it has been fixed: https://github.com/microsoft/vcpkg/issues/19552

    Context: when run-cmake launches CMake on Windows with the vcpkg toolchain, unless CC/CXX env vars are already defined, the environment is setup for the MSVC toolset by running the vcpkg env --triplet <triplet> command.

    Unfortunately this command got broken in vcpkg aftert his commit, and when invoked it fails with what you reported:

    Error: get_directories_non_recursive(D:\a\path\\vcpkg_installed\x64-windows\tools): 
The system cannot find the path specified.

    Using a vcpkg repository Git commit more recent than e52d3b24cb45d1e5c8a6eddcce1b12bf570608da contains the fix.
