This is easy to explain.

When compiling a program that uses a library, the compiler needs to
know the "function declarations" for that library. Those declarations
are in the source code for the library.

As long as you are not compiling anything, you don't need any source
code (source code takes a lot of disk space!). So it would be a huge
waste of space to always include this.

To make it easier the source code is usually split into "headers" and
"source". The headers contain the above mentioned declarations, so
someone compiling a program using a library will not need to install
the full sources of the library but only the headers (takes a lot less

But still, it would be a waste of disk space to always include this in
the libraries, because it is only needed when compiling programs.

Now, build instructions always say you need the headers, however
different distributions package headers under different names. Many
distributions call it "package name"-devel, but others have different
names. So you need to know what your distribution call the header
packages. The build instructions can not include all the possible
package names because it depends on what distribution you are
compiling under.
