COMP: fix ftd2xx.lib copy at compile time
On some windows systems, the command cmake -E copy
within copy_ftd2xx_static_command
renames the ftd2xx.lib
file as lib\${BUILD_TYPE}
instead of copying it within
the directory of the same name. Because of this, the directory
can not be created in the future for other libraries, explaining
the high number of compilation errors (~50)
Placing a \
at the end of the destination directory should fix
this issue.
