linking glbinding with cmake

I'm trying to use glbinding in my own project. I'm using cmake to build everything. The problem is linker cannot find this library. Probably I don't build library thus it cannot be linked, but I don't know how to achive that. I've written linking code according to https://github.com/hpicgs/glbinding#linking-binaries.

Cmake:

set(SOURCE_FILES main.cpp)

add_executable(AKOpenGLEngine ${SOURCE_FILES})

set(CMAKE_PREFIX_PATH ${CMAKE_MODULE_PATH} glbinding )
find_package(glbinding REQUIRED)
include_directories(${GLBINDING_INCLUDES})
target_link_libraries(AKOpenGLEngine glbinding ${GLBINDING_LIBRARIES})

Error:

Linking CXX executable AKOpenGLEngine
ld: library not found for -lglbinding

main.cpp:

#include <glbinding/gl/gl.h>

int main(void) {
    glbinding::Binding::initialize();
    exit(EXIT_SUCCESS);
}

My current project structure:

Have you tried to remove the glbinding from target_link_libraries? ${GLBINDING_LIBRARIES} should be sufficient; it passes <your_specific_file_path_to_glbinding_library> to the linker. With -lglbinding the linker searches for a library within some default directories, your glbinding or build directory not included, thus throwing a library not found. To verify the content of ${GLBINDING_LIBRARIES} you can print it to cmake output, e.g., via message(STATUS ${GLBINDING_LIBRARIES}). However, i also suggest to integrate glbinding as external project as suggested by @janisz.

EDIT: sorry, didn't see the valid, but collapsed answer of @jet47
