# 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
|
|
# - adds include directories to the library target
