I added a line to my script to delete all of /tmp/mesa/lib64/libGL.so*
after I build mesa and before I build VTK.
I delete everything in the VTK build directory before the build.
The test passed with mesa's libGL.* deleted.
libOSMesa still tried to pull in libGL.so so it got nvidia's library.
I took a look at src/mesa/drivers/osmesa/Makefile and it adds
$(OSMESA_LIB_DEPS) to the build line.
This is defined in configs/default as :
OSMESA_LIB_DEPS = $(EXTRA_LIB_PATH) -L$(TOP)/$(LIB_DIR) -l$(GL_LIB)
I removed the -l$(GL_LIB) from the end of this line and reran my script.
The build failed with :
