[vtkusers] Find Mangled Mesa

[Berk Geveci]

We had issues with mangling newer Mesa libs. I don't know when but mangling
broke in Mesa at one point. I recommend using Mesa 6.0. As for the name of
the GL library created by Mesa, you should be able to set it. This is done
by editing Make-config, I believe. Here is what I have in my Make-config:

linux:
        $(MAKE) $(MFLAGS) -f Makefile.X11 targets \
        "GL_LIB_NAME = MGL" \
        "OSMESA_LIB_NAME = MOSMesa" \
        "GL_LIB = libMGL.so" \
        "GLU_LIB = libMGLU.so" \
        "GLUT_LIB = libMglut.so" \
        "GLW_LIB = libMGLw.so" \
        "OSMESA_LIB = libMOSMesa.so" \
        "CC = gcc" \
        "CXX = g++" \
        "CFLAGS = -DUSE_MGL_NAMESPACE -O3 -ansi -pedantic -fPIC -ffast-math
-D_P
OSIX_SOURCE -D_POSIX_C_SOURCE=199309L -D_SVID_SOURCE -D_BSD_SOURCE
-DUSE_XSHM -D
PTHREADS -I/usr/X11R6/include" \
        "CXXFLAGS =  -DUSE_MGL_NAMESPACE -O3 -ansi -pedantic -fPIC
-ffast-math -
D_POSIX_SOURCE -D_POSIX_C_SOURCE=199309L -D_SVID_SOURCE -D_BSD_SOURCE" \
