Summary0015682: [biicode] Ninja generator uses relative paths in target description when including parent directory
DescriptionThis is the typical directory tree that biicode uses:

CMakeLists.txt
 - bii
   |
   - cmake
     |
     - biicode.cmake
     - CMakeLists.txt
   - build
- bin
- lib

Biicode starts from bii/cmake/CMakeLists.txt which includes bii/cmake/biicode.cmake which then adds the top-level CMakeLists.txt as a subdirectory.

bin and lib are set to CMAKE_RUNTIME_OUTPUT_DIRECTORY and CMAKE_ARCHIVE_OUTPUT_DIRECTORY respectively.

When using the ninja generator with this layout, relative paths are inserted into the build.ninja file, for example:

#############################################
# Link the executable ../../bin/main

build ../../bin/main: C_EXECUTABLE_LINKER build_dir/CMakeFiles/main.dir/main.c.o
  POST_BUILD = :
  PRE_LINK = :
  TARGET_PDB = main.dbg
# =============================================================================
# Target aliases.

However, the all target specifies the absolute path to the output file:

#############################################
# The main all target.

build all: phony /Users/smspillaz/Source/polysquare/cmake-ninja-test/bin/main

Which causes ninja to fail:

ninja: error: '/Users/smspillaz/Source/polysquare/cmake-ninja-test/bin/main', needed by 'all', missing and no known rule to make it
Steps To ReproduceTarball of reduced testcase included.

$ cd bii/
$ mkdir build
$ cd build/
$ cmake ../cmake -G
$ ninja
Additional InformationGranted, this is a strange build configuration, however biicode uses it and it doesn't appear to me that there is any other way of doing what they want to do without breaking their interface.
