I have a program built within CMake that generates some code. I need
this generated code to compile some other libraries. The problem I'm
having is setting the dependency of the generated source file to its
compiler. This is what I have currently:
# This is the helper compiler
ADD_EXECUTABLE(ExtractSymbolsFromXML ExtractSymbolsFromXML.cc)
TARGET_LINK_LIBRARIES(ExtractSymbolsFromXML Dataflow_Network)
# Get the full path to the ExtractSymbolsFromXML executable
GET_TARGET_PROPERTY(ExtractSymbolsFromXML_exe
ExtractSymbolsFromXML ${CMAKE_BUILD_TYPE}_LOCATION)
# Get the path to the executable, so that I can stuff the
generated file in the same place
GET_FILENAME_COMPONENT(binary_path ${ExtractSymbolsFromXML_exe} PATH)
SET(Loader_cc "${binary_path}/Loader.cc")
SET_SOURCE_FILES_PROPERTIES(
${Loader_cc}
PROPERTIES GENERATED TRUE
)
ADD_CUSTOM_COMMAND(
OUTPUT ${Loader_cc}
COMMAND ${ExtractSymbolsFromXML_exe} -o ${Loader_cc}
# This is where I get hung up.
MAIN_DEPENDENCY ${ExtractSymbolsFromXML_exe}
COMMENT "Generating static loader file: ${Loader_cc}"
)
ADD_LIBRARY(StaticHelper Loader.h ${Loader_cc})
==================================================================
I can't seem to get the dependency for ${Loader_cc} right. Any ideas
of what I'm doing wrong?
Thanks,
James
