GLVis makefile targets:
make
make status/info
make install
make app
make clean
make distclean
make style
Examples:
make -j 4
Build GLVis using the current configuration options from MFEM.
(GLVis requires the MFEM finite element library, and uses its compiler and
linker options in its build process.)
make status
Display information about the current configuration.
make install PREFIX=<dir>
Install the glvis executable in <dir>.
make app
Build a Mac OS application bundle.
make clean
Clean the glvis executable, library and object files.
make distclean
In addition to "make clean", remove the local installation directory and some
run-time generated files.
make style
Format the GLVis C++ source files using the Artistic Style (astyle) settings
from MFEM.
