On Linux. On MaxOSX and FreeBSD not at all, where the dl functions are
in libSystem and
CMake/shared/modules will define the CMAKE_DL_LIBS which a very high

Link with *-ldl*.
specifying just the library name adds it as a -L option

But so, who defined the dl target ?

Hi,
I would use ${CMAKE_DL_LIBS} in target_link_libraries:

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
