# some of these macros are inspired from the boost/cmake macros

# this macro adds external dependencies to a static target,
|
||
# compensating for the lack of a link step when building a static library.
|
||
# every compiler has its own way of doing it:
|
||
# - VC++ supports it directly through the static library flags
|
||
# - MinGW/gcc doesn't support it, but as a static library is nothing more than an archive,
|
||
# we can simply merge the external dependencies to our generated target as a post-build step
|
||
# - for other compilers and OSes, static build is not encouraged so we don't try to
|
||
# pre-link dependencies, we just "link" them so that the SFML samples can compile
|

# out-of-the-box (CMake forwards the dependencies automatically)
