inclusion of crypto ++ library in ns3

How to include cryptography libraries like crypto++ using cmake in ns3.

[Gabriel Ferreira]

If you don't care about linking it to everything, just dump the following in the directory CMakeLists.txt that you want to link it.

find_library(CRYPTOPP crypto++)

link_libraries(${CRYPTOPP})

If you care, then read the manual.

Thank you . It worked for me when i used 

find_package(PkgConfig REQUIRED)

pkg_check_modules(Cryptopp REQUIRED IMPORTED_TARGET libcrypto++) 

target_link_libraries(your_application PUBLIC PkgConfig::Cryptopp)
