-# The CMakeLists.txt shipped with cryptopp pollutes our option list and installation list,
-# so we made our own one. This is basically a trimmed down version of the shipped CMakeLists.txt
-# The differences are:
-#  - removed support for legacy CMake versions
-#  - removed support for 32-bit
-#  - removed -march=native flag
-#  - removed rdrand module.asm as a workaround for an issue (see below)
-#  - added prefix "CRYPTOPP_" to all option names
-#  - disabled testing
-#  - disabled installation
-#  - disabled documentation
-#  - configured to build a static library only
