# This script can be used to create static executables linking to the static
# OpenBabel3 library.
#
# This script requires OpenBabel to be build and installed. For example:
#
# cd openbabel
# mkdir build
# cd build
# cmake -DBUILD_SHARED=OFF -DCMAKE_INSTALL_PREFIX=/home/me/some/path ..
# make
# make install
#
# To compile your static executable:
#
# cd myproject
# mkdir build
# cd build
# cmake -DOpenBabel3_DIR=/home/me/some/path/lib/openbabel ..
# make
#
# All plugins are inside the static libopenbabel.a but the symbols for the
# plugin classes have to be undefined. Plugins can be disabled by removing
# the class names from the format_classes, descriptor_classes, ... lists below.
#
# This line is required for cmake backwards compatibility.
