[CMake] CMAKE_EXE_LINKER_FLAGS for shared libraries?

[Robert Dailey]

Another issue...

At what point is it most important for the values of
CMAKE_SHARED_LINK_FLAGS to exist? I set the value of this variable before
my call to add_library(), however after that at some point the flags will
get reverted because I'm stepping out of function scope. Does it need to
exist up to the end of the current cmake script? My flow is basically this
(pseudo call stack):

Enter CMakeLists.txt
- Call define_project() function (in a separate cmake module)
- - Call ignore_libs() function
- - - Set CMAKE_SHARED_LINK_FLAGS with PARENT_SCOPE
- - Call create_target() function
- - - Call add_library() command
Leave CMakeLists.txt

I've done some testing and I find that before the call to add_library(), my
flags are setup properly in the CMAKE_SHARED_LINK_FLAGS variable.
