[cmake-developers] Appending to LINK_FLAGS property of a target doesn't seem to work correctly

[Dan Liew]

Hi,

I noticed recently is you do something like this

add_executable(foo a.cpp b.cpp)
set_property(TARGET shell APPEND PROPERTY LINK_FLAGS "-fopenmp")
set_property(TARGET shell APPEND PROPERTY LINK_FLAGS "-static")

then the flags that end up being passed to the compiler during linking
are like this.

gcc -g -O0 -fopenmp;-static

It looks like when using the property with APPEND it becomes a list
but when emitted the list isn't expanded properly. I noticed this
using CMake 3.4.3 using the "Unix Makefile" generator.

Is this intentional or is this a bug?

Thanks,
Dan.
