Cmake link library target link error

Question

Hi I have problem with linkg Glfw and other libraries using cmake. From command line i compile like this

g++ main.cpp -lGL -lGLU -lGLEW -lglfw

Answer 1

The syntax for target_link_libraries is:

target_link_libraries(your_executable_name libraries_list)

And you don't have to add add_definition statements (target_link_libraries adds this options)

There are also some useful variables provided by OpenGL and GLEW packages.

Your CMakeLists.txt should be like:

cmake_minimum_required (VERSION 2.6)
project (test)

find_package(OpenGL REQUIRED)
find_package(GLEW REQUIRED)

include_directories(${OPENGL_INCLUDE_DIR} ${GLEW_INCLUDE_DIRS})

add_executable(test
    main.cpp
)

target_link_libraries(test ${OPENGL_LIBRARIES} ${GLEW_LIBRARIES})

One important detail to keep in mind is to place the target_link_libraries after the add_executable (or add_library) line.
