I just realized that my problem might be related to a circular dependency I
hadn't noticed before. It was reported by make as "compiler depends on
compiler" which didn't make sense to me.
ADD_LIBRARY(lib_a ${source_files})
ADD_TARGET_LIBRARY(lib_a lib_helper)
ADD_EXECUTABLE(compiler compiler.cc)
ADD_TARGET_LIBRARY(compiler lib_a)
GET_TARGET_PROPERTY(compiler_location compiler ${CMAKE_BUILD_TYPE}_LOCATION)
ADD_CUSTOM_COMMAND(
OUTPUT source.cc
COMMAND ${compiler_location} -o source.cc
DEPENDS compiler
)
ADD_LIBRARY(lib_helper source.cc)
=====================================
Here's the dependency chain:
lib_helper <- source.cc
source.cc <- compiler
compiler <- lib_a
lib_a <- lib_helper !!!! Circular dependency :(
I'll need to refactor some code before I can address this again. I'm hoping
that once I do this, all will become well in the world. If I still have
problems, once I remove the circular dependency, I'll come asking again.
Thanks for everyone's suggestions and help! This is why I like the CMake
mailing list so much.
