Ninja generator sets the name to objectpath.d
cmGlobalNinjaGenerator::EncodeDepfileSpace(objectFileName + ".d");
WindRiver sets the dep file name to objectDir/SourceName.d, so the ".obj" in "DEP_FILE = path/BaseName.c.obj.d" must be removed
Armcc just uses base name in the same directory as the command runs, "BaseName.d". -depend_dir= can be used to control the directory for C but not asm.
The workaround is to patch the generated build.ninja
A proper solution is using new variables similar to above. (Just examples, not figured out <ARCH> etc)
WindRiver (not added to CMake):
SET (CMAKE_<LANG>_<COMPILER_ID>_DEPFILE_PATTERN <OBJECT_DIR>/<SOURCE_FILE_NAME>.d )
Armcc (RVDS patch exists for CMake):
SET (CMAKE_DEPFILE_FLAGS_C -depend_dir=<OBJECT_FULL_DIR> --depend_format=unix)
SET (CMAKE_C_ARMCC_DEPFILE_PATTERN <OBJECT_FULL_DIR>/<SOURCE_BASE_NAME>.d )
SET (CMAKE_DEPFILE_FLAGS_ASM --depend_format=unix)
SET (CMAKE_ASM_ARMCC_DEPFILE_PATTERN <SOURCE_BASE_NAME>.d )
Note: <OBJECT> is replaced in CMAKE_C_ARMCC_DEPFILE_PATTERN (but adding a semicolon), but not <OBJECT_DIR> (as that is evaluated after FLAGS/DEFINES) so it is a little more than just add new variables.
The workaround for armcc could therefore not use CMAKE_DEPFILE_FLAGS_C, the -depend_dir flag was added to normal FLAGS
