My initial reaction to Roger's post was to say that CMAKE_DL_LIBS was created very early in CMake and I think a module like FindLibDl would supersede it. However, Chuck raises a valid point. The dlfcn.h header may be in a toolchain-defined path so "finding" it ourselves may get the wrong one. We don't have find modules for "unistd.h" for example. Perhaps it is simplest to update the documentation of CMAKE_DL_LIBS to explain this. -Brad -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
