Summary: ninja does not rebuild external projects
Description:
External projects are not rebuilt when their sources change when using the ninja
generator (using CMake 2.8.8-rc2). It appears that even when removing the build
stamp to force a build, ninja is not re-run for the external project.
When using the Unix Makefiles generator, all is well.
Steps to Reproduce:
- Set up an external project using the following snippet:
ExternalProject_Add(foo
DEPENDS ${BUILD_FOO_DEPENDENCY}
SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/foo
BINARY_DIR ${CMAKE_CURRENT_BINARY_DIR}/foo
INSTALL_DIR ${CMAKE_INSTALL_PREFIX}
)
ExternalProject_Add_Step(foo forcebuild
COMMAND ${CMAKE_COMMAND}
-E remove ${CMAKE_CURRENT_BUILD_DIR}/foo-prefix/src/foo-stamp/foo-build
DEPENDEES configure
DEPENDERS build
ALWAYS 1
)
- Generate two build trees; one with ninja, and one with makefiles.
- Build both build trees.
- Touch a source file in the subproject
- Rebuild both build trees.
The makefiles build tree rebuilds the external project 'foo'.
The ninja build tree reports:
[1/1] Performing forcebuild step for 'foo'
...and does not rebuild 'foo'.
