Summary0014553: add_subdirectory fails when using Ninja generator
DescriptionThis is the setup:

./folder1/CMakeLists.txt:
  cmake_minimum_required(VERSION 2.8)
  set(LIBRARY_OUTPUT_PATH "${CMAKE_CURRENT_SOURCE_DIR}/libs/")
  add_subdirectory(../folder2 ${CMAKE_CURRENT_BINARY_DIR}/folder2)

./folder2/CMakeLists.txt:
  project(foo)
  add_library(foo foo.cpp)

./folder2/foo.cpp:
  int main() {}
Steps To ReproduceWhen I run cmake with the Unix Makefiles generator, everything works fine:

~/tmp/problem/folder1/build❯ cmake ..
-- The C compiler identification is GNU 4.8.2
-- The CXX compiler identification is GNU 4.8.2
...
-- Configuring done
-- Generating done
-- Build files have been written to: /home/jan/tmp/problem/folder1/build

~/tmp/problem/folder1/build❯ make
Scanning dependencies of target foo
[100%] Building CXX object folder2/CMakeFiles/foo.dir/foo.cpp.o
Linking CXX static library /home/jan/tmp/problem/folder1/libs/libfoo.a
[100%] Built target foo

However, using the Ninja generator doesn't work:

~/tmp/problem/folder1/build❯ cmake -GNinja ..
-- The C compiler identification is GNU 4.8.2
-- The CXX compiler identification is GNU 4.8.2
...
-- Configuring done
-- Generating done
-- Build files have been written to: /home/jan/tmp/problem/folder1/build

~/tmp/problem/folder1/build❯ ninja
ninja: error: '../libs/libfoo.a', needed by 'all', missing and no known rule to make it
Additional Information~/tmp/problem/folder1/build❯ ninja --version
1.4.0

~/tmp/problem/folder1/build❯ cmake --version
cmake version 2.8.12
