Linking statically OpenSSL crypto library in CMake

Question

I want to statically link the libraries listed below:

set_target_properties(exec PROPERTIES LINK_SEARCH_START_STATIC 1)
set_target_properties(exec PROPER         


        

Answer 1

The CMake documentation starting with version 3.4 on the FindOpenSSL page says:

Set OPENSSL_USE_STATIC_LIBS to TRUE to look for static libraries.

(Assuming if they are found they will be used)

Example:

cmake_minimum_required(VERSION 3.4)
project(Foo)

set(SOURCE_FILES main.cpp)

set(OPENSSL_USE_STATIC_LIBS TRUE)
find_package(OpenSSL REQUIRED)

add_executable(${PROJECT_NAME} ${SOURCE_FILES})
target_link_libraries(${PROJECT_NAME} OpenSSL::Crypto)
