C++ CmakeLists build error "/usr/bin/ld: cannot find -lglfw"

Hi all,

I'm trying to build my project which uses mujoco with cmake, and I'm getting the error:

Code:

~ /usr/bin/ld: cannot find -lglfw

I've searched around the forum and internet overall, and found cmake examples:

• http://www.mujoco.org/forum/index.php?threads/c-makefile-cmakelists-txt.3840/
• http://www.mujoco.org/forum/index.php?threads/cmake-request.3361/
  
• https://github.com/atabakd/MuJoCo-Tutorials

Although my cmake files match these ones, I still have a problem with lglfw for some reason. I include relevant snippets from my CmakeLists.txt

Code:

######################################################
# define the include directory of all ${CATKIN_PKGS} #
######################################################
include_directories(
    ${PROJECT_SOURCE_DIR}/include
    ${catkin_INCLUDE_DIRS}
    ${Eigen_INCLUDE_DIRS}
    $ENV{MUJOCO_PATH}/include
)

########################################################
# manage the creation of the libraries and executables #
########################################################
set(USE_GL 1)

link_directories($ENV{MUJOCO_PATH}/bin)

#Finding main mujoco library
if(${USE_GL})
    file(GLOB LIB_MUJOCO $ENV{MUJOCO_PATH}/bin/libmujoco[0-9][0-9][0-9].so)
else()
    file(GLOB LIB_MUJOCO $ENV{MUJOCO_PATH}/bin/libmujoco[0-9][0-9][0-9]nogl.so)
endif()
#Showing mujoco library found
message(STATUS "MuJoCo lib: " ${LIB_MUJOCO})

add_subdirectory(src)

And from src/CmakeLists.txt:

Code:

set(BIN_NAME mujoco_finger_test)

add_executable(${BIN_NAME} ${BIN_NAME}.cpp)
target_link_libraries(${BIN_NAME} ${LIB_MUJOCO})

# Standard libraries for GL
target_link_libraries(${BIN_NAME} GL GLU glut )

# Additional libraries from mujoco package
target_link_libraries(${BIN_NAME} libglew.so libglfw.so.3 libglewegl.so libglewosmesa.so)

Does anyone see what is missing, or is incorrect? Any idea why the error is thrown?

Thanks!
