Summary: [biicode] Ninja generator uses relative paths in
target description when including parent directory
Description:
This 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 Reproduce:
Tarball of reduced testcase included.
$ cd bii/
$ mkdir build
$ cd build/
$ cmake ../cmake -G
$ ninja
Additional Information:
Granted, 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.
