[CMake] Installing CMake in Ubuntu Linux from command-line via wget

[Osman Zakir]

Okay, thanks.

So how about this as the command?

"
RUN wget https://cmake.org/files/v3.12/cmake-3.12.3-Linux-x86_64.tar.gz  \
    && tar xzf cmake-3.12.3-Linux-x86_64.tar.gz  \​
    && rm -rf cmake-3.12.3-Linux-x86_64.tar.gz  \​
    && cd cmake-3.12.3-Linux-x86_64  \​
    && apt-get install \​
    && ./bin/cmake --version
"
I think I'll need the apt-get install part to install the library.  Is this true?

If you want to stick to your original method you need to add some
command line arguments to tar to tell it that is is extracting a
compressed file.

The binary is then available within the extracted directory.

Original command becomes:

RUN wget https://cmake.org/files/v3.12/cmake-3.12.3-Linux-x86_64.tar.gz  \
    && tar xzf cmake-3.12.3-Linux-x86_64.tar.gz  \
    && rm -rf cmake-3.12.3-Linux-x86_64.tar.gz  \
    && cd cmake-3.12.3-Linux-x86_64  \
    && ./bin/cmake --version


tar options:
x - Extract
z - Archive type is gzip (may be optional, depending on version of tar)
f - The file to extract (tar will try and open whatever follows this
argument so it MUST come last in this case)
