Hi @fmattiussi -- I'm really sorry for the delay here.

It looks like you're using the an 0.13.0-rc1 version of the library, which unfortunately does not contain the dependencies needed to build the tests. This is a problem, thank you for the report.

To get around this, you can opt to not build the tests if you don't want/need to run them yourself. The CMake options you want to define are:

• CPP-NETLIB_BUILD_TESTS: Set this to OFF

If you're doing this on the command-line with cmake, it would be an option like:

cmake -DCPP-NETLIB_BUILD_TESTS=OFF <rest of the options>

Does that help?

+1 for this issue, still present in the 0.13.0-final release

Ran into the same issue.

+1 for 0.13.0-final

It seems like the entire deps/ directory is empty in the last few releases.
To work around this I did the following:

git clone https://github.com/cpp-netlib/cpp-netlib.git
cd cpp-netlib
git checkout cpp-netlib-0.13.0-final
git submodule init
git submodule update
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ ..
make -j13

and now I can build the project without errors.

Right. It looks like there's enough folks running into this that I'm going to spend a little bit of time to attempt to make this better.
