# To use this, do the following the first time:

# % mkdir build
# % cd build
# % cmake ..
# % cmake .. -DCMAKE_BUILD_TYPE=release
# % make (install)
#
# To only build C libraries and executables, replace the 3rd cammand above with
# % cmake .. -DCMAKE_BUILD_TYPE=release -DC_ONLY=1
#
# After doing this once can do the following to recompile
# % cd <top level evio dir>
# % cmake --build build (--target install)
#
#
# Set the path in which to install.
# This can be overridden on command line (in build/cmake dir) with:
# % cmake -DCMAKE_INSTALL_PREFIX=<my_dir> ../..
# The installation will default to the CODA env variable if it's defined
# This can be overridden on command line (in build dir) with:
# % cmake -DCODA_INSTALL=<my_dir> ..
# % make install
