cpp-netlib 0.13 'cxxopts.hpp' file not found #include "cxxopts.hpp" after using submodule init and update

[belalshehab]

Hello, I can't compile the latest stable 0.13 build.
the error is /cpp-netlib/libs/network/example/http_client.cpp:18:10: 'cxxopts.hpp' file not found
#include "cxxopts.hpp" fetal error

Note that I got the source files using git submodule as follows
$ git clone https://github.com/cpp-netlib/cpp-netlib
$ cd cpp-netlib
$ git submodule init
$ git submodule update

any help?

My fix was either one or the combinations of root privileges and/or cloning off of https://github.com/glynos/cpp-netlib and doing the documented steps.
As such, both sudo make and sudo make test went to completion with no errors

You can download the project cxxopts and set in CMakeLists.txt like this. Notice that this project relies on version 1.x but not 2.x.

git clone git@github.com:jarro2783/cxxopts.git
git checkout v1.4.4

vim ./CMakeLists.txt
