Summary: [ninja] wrong dependency management with imported
targets from external project or custom target
Description:
Here is a simple CMakeLists to reproduce my problem:
# in my case, this line is actually an ExternalProject_Add
add_custom_target(outfile COMMAND gcc ${CMAKE_CURRENT_SOURCE_DIR}/lib.c
-shared -o liboutfile.so)
add_library( mylib SHARED IMPORTED )
set_property( TARGET mylib PROPERTY IMPORTED_LOCATION liboutfile.so )
add_dependencies( mylib outfile )
add_executable( testexe test.c )
target_link_libraries( testexe mylib )
This ensures that before we try to link with the mylib target, the outfile
target is built. Except it works only with the Unix Makefiles generator but not
with the Ninja one.
With Ninja I get this error before it tries to do any work:
ninja: error: 'liboutfile.so', needed by 'testexe', missing and no known
rule to make it
I'm attaching a simple and complete test project to reproduce.
Steps to Reproduce:
1. download and uncompress the attached testproj
2. configure with the Ninja generator
3. try build with ninja and get an error
