CMake - Specifying Linker / Linker Flags during Cross-Compile - c++

I am in the process of converting out previous build system (Makefiles) to CMake. I am trying to specify the Linker and Linker Flags for CMake and am not sure if I am using the correct syntax/variables. I have included my original Makefile (which compiles and genreates the executable) but when attempting to do the smae with CMake I am getting errors.
Here is the error:
Linking CXX executable discoveryService
/home/projects/OMAP- L137/timesys/SDK/omapl137_evm/toolchain/bin/../../toolchain/lib/crt1.o: In function `_start':
(.text+0x34): undefined reference to `main'
collect2: ld returned 1 exit status
make[2]: *** [arm/communications/discoveryService] Error 1
make[1]: *** [arm/communications/CMakeFiles/discoveryService.dir/all] Error 2
make: *** [all] Error 2
The original Makefile used three flags -lpthread -lc & -o If I am understanding correctly the -o just means to name the executable a specific name so with CMake *ADD_EXECUTABLE* I shouldn't need that since we specify the name of the executable there. I have included my 2 CMakeLists and the original Makefile for reference and any help is greatly appreciated since this has stumped me for the second day now..

Makefile error when building Veins project with Omnet++

I've built a number of projects with Veins on Omnet++ without issues at this stage, and I decided to implement CAM messages into a simulation. However, upon building I arrive at the following error:

It's correct in saying that clang-release/src/v2x is a directory, but it has always been so (even before making the recent changes) and it hasn't produced this error.
Other than the MakeFile error, there is no other error in any of the scripts for the project.
You want to create the executable file clang-release/src/v2x but you can't because that file already exists and is a directory.
The name of the file you attempt to create is
v2x$(D)$(EXE_SUFFIX) and nowhere in your Makefile do you have Make variables D or EXE_SUFFIX defined, so they evaluate to empty strings.
Probably you want to make sure you have D and EXE_SUFFIX defined somewhere.
There is a $(CONFIGFILE) you are including, Make finds it but you did not provide the text of it, check if these variables should be defined in there but are not.

CMake compile-time defines

I am new to using CMake and am attempting to transfer our previous Makefiles into CMakeLists. I have one file, *dsplink_defines.txt* that has the following compile-time defines.
*-DOS_LINUX -DMAX_DSPS=1 -DMAX_PROCESSORS=2 -DID_GPP=1 -DOMAPL1XX -DPROC_COMPONENT -DPOOL_COMPONENT -DNOTIFY_COMPONENT -DMPCS_COMPONENT -DRINGIO_COMPONENT -DMPLIST_COMPONENT -DMSGQ_COMPONENT -DMSGQ_ZCPY_LINK -DCHNL_COMPONENT -DCHNL_ZCPY_LINK -DZCPY_LINK -DKFILE_DEFAULT -DDA8XXGEM -DDA8XXGEM_PHYINTERFACE=SHMEM_INTERFACE -DGPP_SWI_MODE -D_REENTRANT -DVERIFY_DATA -DDDSP_DEBUG*
Our previous Makefile took care of this in the following manner and took care of this by using shell cat starting on line 8:

How do I pass these in using a CMakeList
This should work:
file(READ path/to/dsplink_defines.txt defines) #read file into variable 'defines'
string(REPLACE " " ";" defines "${defines}") #turn space separation into CMake list
add_definitions(${defines})
Of course, if you have full control of the file and can change its format to use semicolons for separation instead of spaces, you can do that and skip the string() line (probably speeding up your CMake processing a little bit by this).

Converting Makefile to CMakeLists.txt

I'm using a developement board that has its own libraries. I have installed ROS on it and now I need to use publish/subscribe by including its libraries to the CMakeLists.txt of the package. I have to also note that I use Eclipse for compilation, so the CMakeLists.txt is in that form. Here is the Makefile of hardware library that I want to use in CMakeLists.txt:
DIR=$(shell pwd)/../
INCS = -I.\
-I$(DIR) \
-I$(DIR)/hardware \
-I$(DIR)/hardware/environment \
-I$(DIR)/hardware/environment/cores \
-I$(DIR)/hardware/environment/cores/environment \
-I$(DIR)/hardware/environment/variants \
-I$(DIR)/hardware/environment/variants/sunxi \
-I$(DIR)/libraries \
-I$(DIR)/libraries/Serial \
-I$(DIR)/libraries/SPI \
-I$(DIR)/libraries/Wire \
-I$(DIR)/libraries/LiquidCrystal \
-I$(DIR)/Basibos/include LIBS=../libenvironment.a TARGET=../output/test
OBJS = BasibosAnaProgram
all:
#mkdir -p $(TARGET)
for i in $(OBJS); do echo "$(CXX) $(INCS) $$i.cpp -o $(TARGET)/$$i $(LIBS)"; done
#for i in $(OBJS); do $(CXX) $(INCS) $$i.cpp -o $(TARGET)/$$i $(LIBS); done
clean:
#for i in $(OBJS); do rm -f $(TARGET)/$$i; done
And here is the example CMakeLists.txt that Makefile should be included:
cmake_minimum_required(VERSION 2.4.6)
include($ENV{ROS_ROOT}/core/rosbuild/rosbuild.cmake)
rosbuild_init()
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)
rosbuild_add_library(${PROJECT_NAME} src/Basibos.cpp)
rosbuild_add_library(${PROJECT_NAME} src/HedefeGitme.cpp)
rosbuild_add_library(${PROJECT_NAME} src/Konum.cpp)
rosbuild_add_library(${PROJECT_NAME} src/Robot.cpp)
rosbuild_add_library(${PROJECT_NAME} src/Sonar.cpp)
rosbuild_add_library(${PROJECT_NAME} src/Zaman.cpp)
rosbuild_add_library(${PROJECT_NAME} src/XMLAyiklayici.cpp)
rosbuild_add_executable(srctest RobotKontrol.cpp)
target_link_libraries(srctest ${PROJECT_NAME})
I'm stuck and can't go forward without help. Any help will be greately appreciated. Thanks in advance
Source: http://www.ros.org/wiki/rosbuild/CMakeLists
You have to add the source files in following fashion:
rosbuild_add_library(XmlRpc src/XmlRpcClient.cpp
src/XmlRpcDispatch.cpp
src/XmlRpcServer.cpp
src/XmlRpcServerConnection.cpp
src/XmlRpcServerMethod.cpp
src/XmlRpcSocket.cpp
src/XmlRpcSource.cpp
src/XmlRpcUtil.cpp
src/XmlRpcValue.cpp)

Error generating dependencies with make

I am trying to implement the non-recursive make solution outlined in the paper "Recursive Make Considered Harmful". I'm currently stuck on getting the *.d dependency files to generate. I've provided the makefile, sample module.mk and error below. Any ideas how I can fix this?

It looks as if some module adds types.cpp to SRCS, even though no such source file exists.
As for the warnings, the first time you run this makefile, the dependency files (foo.d) do not yet exist, so Make complains that it can't include them. It's not a problem, and the warnings won't appear in subsequent runs when those files do exist beforehand. To supress the warnings entirely, change include to -include.
