# USE_OPENSSL_MD5 Compile with OpenSSL MD5 support. This will link
# against libcrypto for MD5 support rather than using the local MD5
# support. MD5 support is required to avoid duplicate image files in
# the output xlsx file. To enable this option pass
# `-DUSE_OPENSSL_MD5=ON` during configuration.
#
# USE_STATIC_MSVC_RUNTIME
# Use the static msvc runtime library when compiling with msvc (default off)
# To enable, pass `-DUSE_STATIC_MSVC_RUNTIME` during configuration.
