I'm guessing EXE_INC are compiler options going to gcc, but what is LIB_LIBS?

As you might guess from the names, EXE_LIBS are the libraries for EXE (ie, executables), and LIB_LIBS are the libraries for LIB (ie, for libraries).
What this specifically means is that LIB_LIBS are also linked in.

For example, if you look at src/sampling/Make/options, you should see this:

Code:

LIB_LIBS = \

    -lfiniteVolume \

    -lmeshTools \

    -lsurfMesh \

    -ltriSurface

which means that if you link against the libsampling.so, all these other libraries will also be linked in, without you having to specify them.
You can verify this with 'ldd'.
For example,

Code:

ldd -v lib/linux64GccDPOpt/libsampling.so

should show these LIB_LIBS libraries too.

Where can I learn what all the options / categories are?

Simply learning by example (ie, seeing how they are used in the OpenFOAM code base) worked for me.
