Summary0014662: Problems with TARGET_BASE
DescriptionIf I use the Ninja Generator and the <TARGET_BASE> specifier within the CMAKE_C_LINK_EXECUTABLE in the Platform file for a compiler, then it does not drop the extension (e.g. it expands to "target.elf" instead of "target").

However, if i use the Makefile generator, then it works (the extension is dropped).

 The TARGET_BASE evaluation is here:

 http://cmake.org/gitweb?p=cmake.git;a=blob;f=Source/cmLocalGenerator.cxx;hb=v2.8.12.1#l949 [^]

and expects replaceValues.Target to contain the actual file path. However, the Ninja generator uses a placeholder that ninja later evaluates:

 http://cmake.org/gitweb?p=cmake.git;a=blob;f=Source/cmNinjaNormalTargetGenerator.cxx;hb=v2.8.12.1#l198 [^]

The implementation of TARGET_BASE will have to be refactored to use a separate replaceValues member (or something like that).

 It looks like TARGET_BASE is no longer used by any CMake-provided platform modules. Its implementation could be dropped if it were not for compatibility with third-party code that assumes it exists.

@tisi: What is the need for <TARGET_BASE> in your case?

 I use the TARGET_BASE within the CMAKE_C_LINK_EXECUTABLE (for an embedded system project):

SET(CMAKE_C_LINK_EXECUTABLE
       "dld <CMAKE_C_LINK_FLAGS> <LINK_FLAGS> -@O=<TARGET_BASE>.map <OBJECTS> <LINK_LIBRARIES> -o <TARGET>"
       "ddump -Rv -o <TARGET_BASE>.s19 <TARGET>" )

I added the support for the windriver compiler to CMake (locally, it's not in your repository) and i use two commands for linking. There are two uses for the TARGET_BASE. The first line is the linker command and outputs additionally to the binary a map file. It would be nice to name it "target.map" instead of "target.elf.map". In the second line it is used again to generate an s19 hex-file, which is used to programm an embedded microcontroller. The s19 file is always needed for each executable, and so i decided to add the command here (instead of add_custom_command for each target). Again, it would be nicer if the name could be "target.s19" instead of "target.elf.s19".

This was working fine for a few years now with the "make" generator (we didn't use any other generator yet). Right now we plan to switch to ninja and found that it is not working in the expected way.
