I like the suggested api. One thing to keep in mind, however, is that some of the file system entities Mac programmers perceive as files are actually bundles themselves... For example, the resource files produced by Interface Builder (the *.nib "files") are actually bundles/directories themselves. As a Mac programmer, I think of the *.nib "file" as just another source file... In reality it's a directory with contents, which is supposed to be recursively copied into the correct location of the target bundle at build time. I would expect to be able to add either ''a file or a directory'' as a MACOSX_BUNDLE_CONTENT element in the ADD_EXECUTABLE/ADD_LIBRARY commands. If it's a file it gets copied into the target bundle at the specified location. If it's a directory, same thing, but recursively. This is '''mandatory''' in my opinion because Apple could decide to add, remove or completely reorganize elements within the *.nib file format with their next version of Xcode. I definitely don't want to mirror the hierarchical structure of a *.nib file in my CMakeLists.txt files. I also definitely don't want to be forced into using FILE(GLOB_RECURSE ...) in order to do things on a file by file basis. As a Mac programmer, I don't necessarily know whether one of these things is a file or directory - I can't tell CMake what I don't know, so CMake should definitely be able to handle either. CMake needs to support copying directories verbatim as bundle elements to make this feature worthwhile. | I like the suggested api.

Issue
On Mac there are several different cases of combinations of bundles, frameworks, and unix tools.
The problem is that CMAKE_INSTALL_PREFIX is not enough. Also, when creating bundles and frameworks, auxilary files should be in the proper subdirectory structure.
Notation
- In all examples, the applications are named appl1, appl2, ...
- libraries are named libr1, libr2, ...
- header files are named appl1_header1, appl2_header2, libr1_header1, ...
- there are auxilary files associated with application and library appl1_aux1, appl2_aux2, libr1_aux1, ...
- and some resource files associated with application and library appl1_res1, appl2_res2, libr1_res1, ...
- All versions are ver1, ver2, ...
- All libraries have lib in their name, while frameworks do not. To differentiate, all frameworks will have names FRlibr1, FRlibr2, ...
Cases
Unix tools only
- No issues (just like any other unix)
Bundle only
- Everything in a same directory:
/Applications/
appl1.app/
Contents/
Info.plist
MacOS/
appl1 -> appl1-1
appl1-1
appl1_aux1
appl1_aux2
Resources/
appl1_res1
appl1_res2
- Suggested api:
ADD_EXECUTABLE( appl1 MACOSX_BUNDLE appl1_src1.cxx appl1_src2.cxx ... MACOSX_BUNDLE_CONTENT apple1_aux1 apple1_aux2 apple1_res1 apple1_res2 ) SET_SOURCE_FILES_PROPERTIES( apple1_aux1 apple1_aux2 PROPERTIES MACOSX_BUNDLE_LOCATION MacOSX ) SET_SOURCE_FILES_PROPERTIES( apple1_res1 apple1_res2 PROPERTIES MACOSX_BUNDLE_LOCATION Resources )
Comment: (submitted by david.cole) I like the suggested api. One thing to keep in mind, however, is that some of the file system entities Mac programmers perceive as files are actually bundles themselves... For example, the resource files produced by Interface Builder (the *.nib "files") are actually bundles/directories themselves. As a Mac programmer, I think of the *.nib "file" as just another source file... In reality it's a directory with contents, which is supposed to be recursively copied into the correct location of the target bundle at build time. I would expect to be able to add either a file or a directory as a MACOSX_BUNDLE_CONTENT element in the ADD_EXECUTABLE/ADD_LIBRARY commands. If it's a file it gets copied into the target bundle at the specified location. If it's a directory, same thing, but recursively. This is mandatory in my opinion because Apple could decide to add, remove or completely reorganize elements within the *.nib file format with their next version of Xcode. I definitely don't want to mirror the hierarchical structure of a *.nib file in my CMakeLists.txt files. I also definitely don't want to be forced into using FILE(GLOB_RECURSE ...) in order to do things on a file by file basis. As a Mac programmer, I don't necessarily know whether one of these things is a file or directory - I can't tell CMake what I don't know, so CMake should definitely be able to handle either. CMake needs to support copying directories verbatim as bundle elements to make this feature worthwhile.
Maybe this concept could be generalized to "any file/directory that needs to be copied from source or binary tree into a location relative to the build exe/dll/lib" on any platform. Perhaps naming the features AUXILIARY_CONTENT_FILE and AUXILIARY_CONTENT_LOCATION would be more useful. I could see wanting to have different configuration files copied to where the exe is as part of the build step on Windows or Linux also. It's sort of an easier way of guaranteeing that a file is part of the build tree. Rather than explicit CONFIGURE_FILE or cmake -E copy/copy_directory commands, you could just add a source file as an AUXILIARY_CONTENT_FILE and cmake would make sure it gets copied/configured at build time.
