How to Configure CMake for Linking Boost Libraries in C on Ubuntu?

CMake Configuration for Boost Library Linkage in C Programs on Ubuntu

When linking a C program with the Boost library, you may encounter errors when referencing Boost definitions. To resolve this issue, you need to add the appropriate CMake configurations to your CMake file.

CMake File Configuration

In the CMake file, include the following lines:

find_package(Boost 1.40 COMPONENTS program_options REQUIRED)
include_directories(${Boost_INCLUDE_DIR})
target_link_libraries(my_target_file ${Boost_PROGRAM_OPTIONS_LIBRARY})

FindBoost.cmake

The Boost library comes with a FindBoost.cmake script, which is typically installed in /usr/share/cmake/Modules/. This script automates the process of finding the Boost library and providing the necessary CMake variables.

Detailed Explanation

• find_package(Boost 1.40): Search for the Boost library version 1.40. Replace 1.40 with the appropriate Boost version you are using.
• include_directories(${Boost_INCLUDE_DIR}): Add the Boost include directory to the search path for header files.
• target_link_libraries(my_target_file ${Boost_PROGRAM_OPTIONS_LIBRARY}): Specify that the target executable, my_target_file, should be linked with the Boost library's program_options component.
