how do I eliminate linker error mingw32/bin/ld.exe: cannot find -lSDL

I am trying to build SDL for use with Eclipse. I am trying to remove this linker error:

Beginning Compilation

21:15:53 **** Incremental Build of configuration Debug for project CMD ****
Info: Internal Builder is used for build
g++ "-IC:\\MinGW\\include\\SDL2" -O0 -g3 -Wall -c -fmessage-length=0 -o "src\\CMD.o""..\\src\\CMD.cpp" 
g++ -o CMD.exe "src\\CMD.o" -lmingw32 -lSDL -lSDL2main -lSDL2 

ERROR(s):

c:/mingw/bin/../lib/gcc/mingw32/5.3.0/../../../../mingw32/bin/ld.exe: cannot find -lSDL collect2.exe: error: ld returned 1 exit status 21:15:54 Build Finished (took 1s.36ms)

The most pertinent SO archive source I researched didn't seem to have an actionable answer for my problem, though it had the exact same problem/error: title -- producing the same error message:

c:/mingw/bin/../lib/gcc/mingw32/4.7.0/../../../../mingw32/bin/ld.exe: cannot find -lSDL.

If you click to the authors "solution" for the same error as mine its not clear to me how he solved it.

Any help?
