[CMake] Link directories order

Can that be done without writing the lib suffix explicitly (not cross- 
platform)?

I don't see what you mean, could you make this explicit please?

Does this have something to do with the INSTALL statement? If not, it
is the online example that should be changed.

I defined linker flags that express what I want. I have software
installed in non-standard directories like /sw/lib and /usr/local/lib,
and I do want CMake to look there (cf. LDFLAGS). However, I want CMake
to look in the local directory *first* to link the executable
helloDemo against the lib Hello that has just been built.

Thanks for your help,

Renaud.
