[CMake] CMake: using dlopen

[Franck Houssen]

Hello, 

I have an executable that needs dlopen. 

Googled this a bit: seems (surprisingly) there is no FindDLUtils ?!.. Correct ? If so, why is this ? 
My understanding is that I need to go: 
~BUILD> cmake -DCMAKE_LD_LIBS="-ldl -L/path/to/dl" .. 
which is, basically, telling to CMake where dl is (although this is the job of a build system, no ?!) 

Did I understand correctly ? Did I miss something ?
