How to install C source files and headers?

Question

I've been given these source files and headers. In the README.md the authors explain how to launch the test executables without the need of a proper installation. It is just a make command to run. They explain how to generate the .so files. I think these latter are meant to be used if I wanted to install the APIs at a system level (the definitions should be in api.h ). My question is: where should I copy the shared objects generated by the Makefile and the api.h header? I aim to write a source file from scratch where I use those APIs (eg crypto_sign() ) just including the headers, if it is possible. Thanks

Nowhere.

The project comes with CMake support. Use CMake in your project and just add_subdirectory the repository directory.

Anyway, if you really wish to install the library system-wide, then FHS specifies directory structure on linux. For local system administration use /usr/local/lib for local libraries .so files and /usr/local/include for local C header files.
