Problems installing make in gmp

[Madhurima Mukhopadhyay]

I have installed gmp in my /usr/local.
The commands that I have used are as follows.

In folder /usr/local I did
1.  sudo apt-get update

2. sudo apt-get install g++ m4 zlib1g-dev make p7zip

3. wget https://gmplib.org/download/gmp/gmp-6.1.2.tar.lz

4.  tar xvf /gmp-6.1.2.tar.lz
5. Renaming it as gmp

Then I entered tge gmp folder and ran
1. ./configure
2. make
3. make check
4. sudo make install.

But after this I am getting a message like

Libraries have been installed in:
   /usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Is it an error message?
I cannot resolve it anyhow.
