Converting a Makefile into CMakeLists.txt equivalent - c++

Question

I am working on a project were I maintain a CMakeLists.txt file to keep track of the dependencies when I need to compile.
I recently, started using a new library that I need to integrate in my project. The library comes with some examples on how to compile but this is purely a Makefile. I would like to integrate the logic of the Makefile into my project's CMakeLists.txt file.
The Makefile of this library is as follows:
COMMON=-O2 -I/home/john/.mujoco/mjpro200/include -L/home/john/.mujoco/mjpro200/bin -std=c++11 -mavx -pthread -Wl,-rpath,'$$ORIGIN'
all:
g++ $(COMMON) basic.cpp -lmujoco200 -lGL -lglew /home/john/.mujoco/mjpro200/bin/libglfw.so.3 -o basic
gcc -c -O2 -mavx -I/home/john/.mujoco/mjpro200/include /home/john/.mujoco/mjpro200/include/uitools.c
rm *.o
I would like to convert this Makefile into CMakeLists.txt exactly if possible. I see that they provide some flags for threading (pthread) and I want to keep these flags and settings in my CMakeLists.txt in case they are needed for performance.
Here is my CMakeLists.txt:
cmake_minimum_required (VERSION 2.6.0)
project(myproject)
add_compile_options(-std=c++11) # CMake 2.8.12 or newer
if( CMAKE_COMPILER_IS_GNUCC OR CMAKE_COMPILER_IS_GNUCXX )
add_definitions("-fno-strict-aliasing -Wall")
endif( CMAKE_COMPILER_IS_GNUCC OR CMAKE_COMPILER_IS_GNUCXX )
# optional in case boost is used
find_package(Boost 1.58 EXACT)
find_package(Eigen REQUIRED)
set(mujocoCommon "-O2 -I/home/john/.mujoco/mjpro200/include -L/home/john/.mujoco/mjpro200/bin -std=c++11 -mavx -pthread -Wl,-rpath,'$$ORIGIN'")
set(Mujoco_INCLUDE_DIRS "/home/john/.mujoco/mjpro200/include")
include_directories(${Boost_INCLUDE_DIRS} ${Eigen_INCLUDE_DIRS} ${Mujoco_INCLUDE_DIRS})
link_directories(${Boost_LIBRARY_DIRS})
add_executable(myproject mycode.cpp)
install(TARGETS myproject DESTINATION .)
So I tried to define a variable mujocoCommon similar to the COMMON in the Makefile as well as the Mujoco_INCLUDE_DIRS that I then use in the CMake's include_directories.
Note that in the myproject.cpp I have MuJoCo code and other dependencies that I need to correctly link against. In the Makefile things looks a bit more simpler because in there the code has only MuJoco dependencies.
I need some heads-up on how to add in my CMakeLists.txt the following:
-mavx -pthread -Wl,-rpath,'$$ORIGIN' part of Makefile's COMMON variable.
-lmujoco200 -lGL -lglew /home/john/.mujoco/mjpro200/bin/libglfw.so.3
-c -O2 -mavx -I/home/john/.mujoco/mjpro200/include /home/john/.mujoco/mjpro200/include/uitools.c
Currently with the minimal knowledge on CMake and what I have in my CMakeLists.txt when I compile using "make" I get many errors of the kind:
myproject.cpp:(.text+0xfa9): undefined reference to `glfwSetMouseButtonCallback'
Basically I would like to link (?) my code with MuJoco library as is done in their Makefile.
Thanks.
Edit
In regards with the possible duplicate flag, I added the following flag:
set(Mujoco_LIBRARIES "/home/john/.mujoco/mjpro200/bin")
target_link_libraries(myproject ${Mujoco_LIBRARIES} -lboost_system)
But it didn't solved the problem.
Edit 2:
I have also added this one:
set(CMAKE_CXX_FLAGS "-lmujoco200 -lGL -lglew /home/john/.mujoco/mjpro200/bin/libglfw.so.3")
The errors I am getting:
/usr/bin/x86_64-linux-gnu-ld: cannot find -lmujoco200
/usr/bin/x86_64-linux-gnu-ld: cannot find -lglew

Answer 1

You also need to add the opengl libraries to the link libraries, target_link_libraries. Don't add them with -l.
