How to know library variable names for CMakeLists?

Question

When using CMakeLists to compile an OpenGL project, I have the following line to link glut and gl:

target_link_libraries(my_exe ${OPENGL_gl_LIBRARY} ${GLUT_L         


        

Answer 1

You don't. It is dependent on the find-module for the library.

See here.

Under Writing find modules you see that variables are set in the module. When checking the FindOpenGL.cmake module in your CMake-Modules directory you will see the name of the variable.
