You don't generally need to use link-directories - if you're using

Yes, that is that the former guys wrote and it is really working this
easy way now.
and if not you should be passing full
paths to the library files in target_link_libraries, where you can
specify using the debug, optimized, and general keywords.
For external lib not using cmake i will use something like
/TARGET_LINK_LIBRARIES( Project1 debug
//F:/Extern////Lib1/Debug/test1.lib//
/ optimized //F:/Extern//Lib1/Release/test1.lib
)
/
But i have not tested yet. i suggest to add this to the FAQ because i
missed it there very much.
Ciao,

Instead of hard-coding the paths in your CMakeLists.txt, I'd suggest
using the find_library and find_path (for include_directories) to
attempt to find the libraries in some area, and to allow the developer
to change the library/include paths by editing a cache variable with the
CMake GUI. At least to me, I code my CMakeLists files for all projects
as if the project were open source and might be built by folks who had
just installed the dependencies either a: in their default locations
(where I want to auto-detect them), or b: in some strange location (if
they configured a different install location, I want them to be able to
configure the build of the project similarly.) As a result, I create
Find*.cmake modules for every dependency that provide a
WHATEVER_ROOT_DIR cache variable, used to generate appropriate paths to
pass as "HINTS" to the find_library/path calls, that is not marked as
advanced until the full library is found, as well as the individual
_LIBRARY and _INCLUDE_DIR cache vars that are marked as advanced
automatically in all cases. I've pasted an example below.

---- FindVRPN.cmake ----
# - try to find VRPN library

# Cache Variables:
# VRPN_LIBRARY
# VRPN_SERVER_LIBRARY

# Non-cache variables you might use in your CMakeLists.txt:
