cannot find -lOpenGL::OpenGL
I am running Ubuntu 16.04 and try to install an application that relies on OpenGL via the cmake & make toolschain.
The station has an Nvidia Quadro K2200 and OpenGL is installed via the package manager.
If cmake is run I confirmed that OpenGL is found, however if I try to link my target agains OpenGL via "target_link_libraries" and the rather modern OpenGL::OpenGL imported target,
target_link_libraries(${PROJECT_NAME}
PUBLIC
OpenGL::OpenGL
)
as suggest in the FindOpenGL.cmake file, I receive the error
/usr/bin/ld: cannot find -lOpenGL::OpenGL collect2: error: ld returned
1 exit status
However, if I instead put
target_link_libraries(${PROJECT_NAME}
PUBLIC
GLU
GL
)
it does work. I am suspicious of this since I uses to install the very same version of my programm on another work station also on Ubuntu 16.04 but with another GPU (GTX 780). So I did some digging and found out that
ldconfig -p | grep libGL.so
yielded
libGL.so.1 (libc6,x86-64) => /usr/lib/nvidia-384/libGL.so.1
libGL.so.1 (libc6) => /usr/lib32/nvidia-384/libGL.so.1
libGL.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libGL.so
libGL.so (libc6,x86-64) => /usr/lib/nvidia-384/libGL.so
libGL.so (libc6) => /usr/lib32/nvidia-384/libGL.so
So two questions emerge
Why is the GL lib installed at least partially in a nvidia subdirectory and what does lib32 mean?
Why does cmake find OpenGL but is not able to resolve the imported target but the GL GLU syntax?
thank you for your help
