MinGW: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+

I am attempting to build GCC-5.3.0 on a PC running Windows 10 with MinGW software. I got this error

configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 
0.8.0+.
Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations.  Source code for these libraries can be found at
their respective hosting sites as well as at
ftp://gcc.gnu.org/pub/gcc/infrastructure/.  See also
http://gcc.gnu.org/install/prerequisites.html for additional info.  If
you obtained GMP, MPFR and/or MPC from a vendor distribution package,
make sure that you have installed both the libraries and the header
files.  They may be located in separate packages.

My input was

username@computername /d/gnu/gcc-5.3.0-build
$ ../gcc-5.3.0/configure --target arm-eabi --enable-win32-registry=My
ToolchainName --prefix /f/gnu/out/ --enable-languages=c,c++ --disable
-nls --disable-shared --with-newlib --with-headers=../newlib-2.4.0/ne
wlib/libc/include

Note: /d/ path as my D:/ drive

I have added the path in environment variables

D:\MinGW\bin

I already installed libgmp 5.1.2, libmpfr 3.1.2, and libmpc 1.0.2 from MinGW installation manager

I followed the guide from http://gnutoolchains.com/building/ to build my own GNU toolchains on Windows

The error message is self-explanatory: you need to provide paths to required libraries via --with-* option, like --with-gmp=/d/path/to/gmp. – Andrejs Cainikovs
Thanks. i already found out that i do not have gmp.h file so i had to build my own GMP – user3763113

Download more library package build and install them into a new folder for example /c/gnu/install

gmp-6.1.2.tar.bz2
mpfr-3.1.5.tar.bz2
mpc-1.0.2.tar.gz

1> Build gmp

cd gmp-6.1.2
configure --prefix=/c/gnu/install/
make -j4 install

2> Build mpfr

cd mpfr-3.1.5
configure --prefix=/c/gnu/install/ --with-gmp=/c/gnu/install/ --enable-static --disable-shared
make -j4 install

3> Build mpc

cd mpc-1.0.2
configure --prefix=/c/gnu/install/ --with-gmp=/c/gnu/install/ --with-mpfr=/c/gnu/install/ --enable-static --disable-shared
make -j4 install

Then you configure building gcc with options :

--with-gmp=/c/gnu/install/ --with-mpfr=/c/gnu/install/ --with-mpc=/c/gnu/install/
