I’m trying to create a docker image like this:

FROM debian:bookworm-slim
    
RUN apt-get update && apt-get install -y git cmake
RUN git clone https://github.com/user/REPO.git
RUN cd REPO
RUN rm -Rf build
RUN mkdir build
RUN cd build
RUN cmake ..
RUN make
RUN mv executable /usr/local/bin
RUN cd ~
RUN rm -Rf REPO

However it breaks at “RUN cmake ..”
With the following error:

#0 0.275 CMake Warning:
#0 0.275   Ignoring extra path from command line:
#0 0.275
#0 0.275    ".."
#0 0.275
#0 0.275
#0 0.275 CMake Error: The source directory "/" does not appear to contain CMakeLists.txt.

I have no idea what is going on. When I run this directly on the terminal it compiles completely fine.
