<pre>When "Linking C executable ../../../../bin/point-sprite", the following errors
are thrown:
../../../../lib/libpiglitutil_gl.so.0: undefined reference to `gbm_bo_unmap'
../../../../lib/libpiglitutil_gl.so.0: undefined reference to `gbm_bo_map'
collect2: error: ld returned 1 exit status
make[2]: *** [bin/point-sprite] Error 1
This is due to CMakeList.txt assuming that gbm >= 12.1 includes gbm_bo_map and
gbm_bo_unmap, but that is not the case with Mali drivers (Mali-T628, Mali-T624,
Mali-450, Mali-T760). GPU drivers can be publicly found here:
<a href="https://developer.arm.com/products/software/mali-drivers/user-space">https://developer.arm.com/products/software/mali-drivers/user-space</a>
Instead of checking for GBM_VERSION >= 12.1, it should be possible to
CHECK_FUNCTION_EXISTS(gbm_bo_map PIGLIT_HAS_GBM_BO_MAP)</pre>
