What is the equivalent function that generate a "-L" and -rpath flag in g++

Question

When I compile my c++ program using manually written makefile, I use the following command:

LNK_FLAG      = -L $(LIB_PATH) -lnameofmylib
RPATH_FLAG    = -Wl,-rpath,$(LIB_PATH)

and I use make LIB_PATH=/path/to/my/lib to build my program.

Now I want to use cmake to build my program, so, I wonder if there are some mechanisms to do that? or do I have to use set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -L ${LIB_PATH} -lnameofmylib -Wl,-rpath,${LIB_PATH}")?

Too many questions in one post: `-L` and `-l` options are described in @Joel answer, setting `LIB_PATH` for use in makefile may be replaced with `set(LIB_PATH <...> CACHE ...)` in CMake, RPATH handling in CMake is described in [Wiki](https://cmake.org/Wiki/CMake_RPATH_handling). — Tsyvarev, Mar 21 '16 at 07:08

If you want to add a library search path, use link_directories. For linking a library, use link_libraries. This can be portable on any OS or compiler/linker, or less your are using compiler dependend features.
