CMake/build system will typically search the library path, so you
don't need full paths... typically just the name of the library...
should be more like ..

target_link_libraries(Debug ${VTK_LIBRARIES} sri-spatialfft
sri-spatial sri-memory)

Re: [CMake] CMake target_link_libraries items should be quoted or not? Linux/Ubuntu 14.04 cmake 3.4.1

[Petr Kmoch]

Hi,

yes, that is indeed expected behaviour. target_link_libraries() takes a
CMake list of arguments - one library per argument. When you surround the
thing with quotes, it's a single argument (containing some spaces). So for
this call:

target_link_libraries(Debug "${VTK_LIBRARIES} -lsri-spatialfft
-lsri-spatial -lsri-memory")

CMake will instruct the linker to look for a library named " -sri-spatialfft -lsri-spatial -lsri-memory" (one file name
with spaces and semicolons in it). Since such a library does not exist,
that fails.

Without the quotes, each element of the list VTK_LIBRARIES will be a
separate argument to target_link_libraries, as will "-lsri-spatialfft",
"-lsri-spatial", and "-lsri-memory".

Side note: you probably shouldn't be using the -l prefix with arguments to
target_link_libraries(). The arguments are normally supposed to be either
CMake target names, or full paths to the libraries you want to link. No
need to prefix them with linker command-line options, CMake does that for
you accordingly.

[CMake] CMake target_link_libraries() items should be quoted or not? Linux/Ubuntu 14.04 cmake 3.4.1

[Normand Robert]

Reading docs trying to understand why my build works when I write

target_link_libraries(Debug ${VTK_LIBRARIES} -lsri-spatialfft 
-lsri-spatial -lsri-memory)


but does not work when everything is protected in quotes:

target_link_libraries(Debug "${VTK_LIBRARIES} -lsri-spatialfft 
-lsri-spatial -lsri-memory")


which causes an extra library which does not exist to be passed to the 
linker. Is this expected behaviour?
