Did it really build, or did it show compile / linking errors?

Is the binary you are trying to launch actually there. If so, you're binary parsers setting in the project properties might be set to the wrong thing. A little more information about what toolchain you are using would help.

I also have this problem.
My setup is:
-Debian 7 (Wheezy)
-Eclipse with CDT (C++) - installed with apt-get
-libsdl2-dev - installed with apt-get

I only get this error while trying to use a custom library (SDL.h from the libsdl2-dev package).
The library is in /usr/include/SDL2
I have added these links to the Properties->C++ Build->Settings
under both the C++ Compiler->Includes and C++ Linker->Libraries:
Folder: /usr/include/SDL2
File: /usr/include/SDL2/SDL.h

I see in the console that the C++ Linker command issued on "Build" is:

g++  -o "Project_Name"  ./src/main.o   -l/usr/include/SDL2/SDL.h

(This is without the library folder in the C++ Linker, which alone does nothing, but I tried with the folder and without the folder.)

And the error following is:

/usr/bin/ld: cannot find -l/usr/include/SDL2/SDL.h
collect2: error: ld returned 1 exit status

I thought this may be because the "-l" is coming after the file name, but got the same error when manually trying this command while putting the main.o file at the end of the command; indeed, "ld" can not find the file. I did an "updatedb", but that did not fix the issue.

If I take out the C++ Linker libraries, then the C++ Compiler runs fine (using the includes), but when the C++ Linker is invoked I get an error about all of the SDL functions not being found, such as

undefined reference to `SDL_Init'

Okay, posting my thoughts usually helps me, and did so in this case.
For this I will use "SDL2" as an example.

If you want to include a downloaded library then you need to set the following in Project->Properties->C++ Build->Settings:

C++ Compiler->Includes:
-Include Paths (-l): /usr/include/SDL2
-Include Files (-include): SDL.h

C++ Linker->Libaries:
-Libraries (-l): SDL2
-Library Search Path (-L): /usr/lib/i386-linux-gnu
(The full path and filename in my system is: /usr/lib/i386-linux-gnu/libSDL2.so
There is also one at: /usr/local/lib/libSDL2.so
But you do not include the prefix "lib" or the extension ".so")

Note that your search path may be different; you can use the "locate" command to find the path of files.

Hopefully this helps people who have the same error, due to being new at compiling and not knowing the correct syntax of commands called by Eclipse.
