Link error with CMake (undefined symbols), not observed when compiling manually

[david-alvarez-rosa]

I'm trying to link against boost/program_options library with a dummy program main.cpp

#include <boost/program_options.hpp>

int main() {
  boost::program_options::options_description desc("My description");
}

by using the following CMakeLists.txt

cmake_minimum_required(VERSION 3.10)
project(my-project)

find_package(Boost 1.82 REQUIRED)
add_executable(exe "main.cpp")
target_include_directories(exe PRIVATE ${Boost_INCLUDE_DIR})
target_link_libraries(exe ${Boost_LIBRARIES})

And I'm getting the following error

$ cmake -B build
...  [Succeeds]
$ cmake --build build -v
...

clang: error: linker command failed with exit code 1 (use -v to see invocation)

However, surprisingly, when compiling manually it works

$ clang++ -I/opt/homebrew/include -L/opt/homebrew/lib -lboost_program_options main.cpp

I've been using Boost libraries in this same project, so I'm not sure what could be going wrong.

Any pointers appreciated!

I've Boost libraries installed (v. 1.82) directly by Homebrew

$ brew install boost
