How to mix dynamic and static boost libraries in one cmake project? - c++

Question

I'm trying to link my C++ program with static Boost::program_options and dynamic Boost::log libraries.
Here is my CMakeList.txt file:
project(test)
add_executable(testprog "main.cpp")
add_definitions(-DBOOST_ALL_NO_LIB)
set(Boost_USE_STATIC_LIBS ON)
find_package(Boost COMPONENTS program_options)
target_link_libraries(testprog PRIVATE Boost::program_options)
set(Boost_USE_STATIC_LIBS OFF)
add_definitions(-DBOOST_LOG_DYN_LINK)
find_package(Boost COMPONENTS log)
target_link_libraries(testprog PRIVATE Boost::log)
and my main.cpp file:
#define BOOST_ALL_NO_LIB
#include <iostream>
#include <string>
#include <boost/program_options.hpp>
#include <boost/log/trivial.hpp>
int main(int argc, char* argv[])
{
namespace po = boost::program_options;
po::options_description desc("allowed arguments");
desc.add_options()("log", po::value<std::string>(), "log level");
po::variables_map options;
po::store(po::command_line_parser(argc, argv).options(desc).run(), options);
po::notify(options);
if (options.count("log")) {
std::cout << "log level: " << options["log"].as<std::string>() << std::endl;
}
BOOST_LOG_TRIVIAL(info) << "test message";
return 0;
}
I'm getting boost_filesystem.dll is missing from your computer error.
If I get rid of set(Boost_USE_STATIC_LIBS OFF) line, I'm getting unresolved external symbols boost::log.... Looks like Boost_USE_STATIC_LIBS can be set only once during the configuration time, but I just cannot find the way to tell cmake to split static/dynamic libraries...
Thanks.
