CMake linker input file unused because linking not done - c++

Question

I want to transfer an old side project to CMake. Previously it used a Makefile with custom variables, defines and etc. I specified the same flags to compile various configurations. I did it this way:
cmake_minimum_required(VERSION 3.2.2)
project(wise_RK)
set(CMAKE_VERBOSE_MAKEFILE ON)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED True)
set(SOURCES main.cpp devices/RK.cpp LogWriter/LogWriter.cpp)
set(CMAKE_CXX_FLAGS "-DIMA -std=c++11 -Wall -Wextra -c -O2 -MMD -MP -MF '$#.d'")
set(CMAKE_INCLUDE_CURRENT_DIR ON)
include_directories(
structs
devices
LogWriter
/home/data/lib/wise_versioning
/home/data/lib/wisenet
/home/data/lib/wise_log
/home/data/lib/wise_rs_device
/home/data/lib/json
)
# wise_rs_device
add_library(wise_rs_device STATIC IMPORTED GLOBAL)
set_target_properties(wise_rs_device PROPERTIES
IMPORTED_LOCATION "/home/data/lib/wise_rs_device/libwise_rs_device.a"
INTERFACE_INCLUDE_DIRECTORIES "/home/data/lib/wise_rs_device/"
)
# wisenet
add_library(wisenet STATIC IMPORTED GLOBAL)
set_target_properties(wisenet PROPERTIES
IMPORTED_LOCATION "/home/data/lib/wisenet/libwise_net_rs485.so"
INTERFACE_INCLUDE_DIRECTORIES "/home/data/lib/wisenet/"
)
#wise_log
add_library(wise_log STATIC IMPORTED GLOBAL)
set_target_properties(wise_log PROPERTIES
IMPORTED_LOCATION "/home/data/lib/wise_log/Release/GNU-Linux/libwise_log.so"
INTERFACE_INCLUDE_DIRECTORIES "/home/data/lib/wise_log/"
)
add_executable(wise_rk ${SOURCES})
target_link_libraries(wise_rk PRIVATE wise_rs_device wisenet wise_log)
add_definitions(-DSOME_IMPORTANT_DEFINITION)
-D is define of various configurations.
In the Makefile, the list of project object files (not libraries) involved in the assembly was like this:
OBJECTS:=$(shell find * -type f -name "*.cpp" | sed "s/\.cpp/\.o /" | sort)
DEPENDS:=$(addprefix build/$(CONF)/, ${OBJECTS:.o=.o.d})
-include ${DEPENDS}
When I built my CMake:
/usr/local/bin/cmake -E cmake_link_script CMakeFiles/wise_rk.dir/link.txt --verbose=1
/usr/bin/c++ -DIMA -std=c++11 -Wall -Wextra -c -O2 -MMD -MP -MF '$#.d' CMakeFiles/wise_rk.dir/main.cpp.o CMakeFiles/wise_rk.dir/devices/RK.cpp.o CMakeFiles/wise_rk.dir/LogWriter/LogWriter.cpp.o -o wise_rk -rdynamic /home/data/lib/wise_rs_device/libwise_rs_device.a /home/data/lib/wisenet/libwise_net_rs485.so /home/data/lib/wise_log/Release/GNU-Linux/libwise_log.so

I do not know what to do next to solve this kind of problem.

Answer 1

I changed all the .so libs to SHARED. And also removed part of flags -c -O2 -MMD -MP -MF '$#.d' like #Botje wrote. Seems like project built.
