Linux OSMesa cmake: undefined functions when make

[zxx2020]

I'm trying to build glew for osmesa, but at the last step of cd build cmake ./cmake make -j4

the make step reports undefined reference to multiple glX functions. I get these errors whether I use 'make -j4 GLEW_OSMESA=1' or just 'make -j4'. Also is that the correct syntax to set GLEW_OSMESA for make. The readme lists target and variables, but doesn't give an example of how to set them when calling make.

This seems to work on Linux:

$ make SYSTEM=linux-osmesa

cmake does also look fine:

$ cmake .. -DGLEW_OSMESA=Y
