# dependency to the global include directories. Moreover, the extern shared
# libraries are stored in the variable passed as a third parameter. These shared
# libraries can then be copied to a target output path by using the
# SCIQLOP_COPY_TO_TARGET function.

# SCIQLOP_ADD_EXTERN_DEPENDENCY can be used to add a dependency residing in the

# be added.

# The second parameter is the name of the variable where the found shared
# libraries will be added.
#
# The third parameter is the name of the dependency, and the rest of the
# arguments are the same than the FIND_PACKAGE command. In fact they are passed
# as-is to the command.
#
# If the dependency is found, then INCLUDE_DIRECTORIES is called for the
# dependency include directories, and the libraries are added to the
# externLibrariesVar variable. Moreover, if the dependency is a shared library,
# then the dynamic libraries are added to the externSharedLibrariesVar so that
# they can be copied and installed alongside the module. The libraries in this
# variable are ordered so that the real library is before the symlinks to the
# library, so that the copy and install works as expected.
