| Generates a rule to copy each source file from source directory

| to destination directory.

|
| |
|
| Typical use:
| | This page has moved [https://gitlab.kitware.com/cmake/community/wikis/contrib/macros/CopyIfDifferent here]. |
| | |
| <pre>
| |
| SET(SRC_FILES head1.h head2.h head3.h)
| |
| COPY_IF_DIFFERENT( /from_dir /to_dir ${SRC_FILES} IncludeTargets "Includes")
| |
| ADD_TARGET(CopyIncludes ALL DEPENDS ${IncludeTargets})
| |
| </pre>
| |
| | |
| will generate rules that look
| |
| | |
| <pre>
| |
| CopyIncludes: $(CopyIncludes_DEPEND_LIBS) \
| |
| Include\head1.h \
| |
| Include\head2.h \
| |
| Include\head3.h
| |
| | |
| Include\head1.h:
| |
| @echo Building Copying head1.h /to_dir head1.h...
| |
| cmake.exe -E copy_if_different /from_dir/head1.h /to_dir/head1.h

| </pre>

| The macro code is:

| |
| # FILES - names of the files to copy
| |
| # TODO: add globing.
| |
| # TARGETS - List of targets
| |
| # TAGS - Since only the file name is used
| |
| # to generate rules, pre-pend a user
| |
| # supplied tag to prevent duplicate rule errors.
