The project contains an initial CMake configuration file along with some source files in a single directory: > root -> CMakeLists.txt # Initial CMake configuration -> interpolate.cpp # Source file for 'interp' library -> interpolate.h # Header file for 'interp' library -> main.cpp # Source file for the executable -> steps/
Cmake verbose download#
Run the following git command to download it to your system: $ git clone Source FilesĪ small C++ sample project has been setup on GitHub to accompany this tutorial. Upon completing this tutorial, you will have built up enough knowledge to be able to configure the compiler to your exact specifications for building a project with CMake.
Cmake verbose how to#
Selecting a Compiler and Inspecting its Properties We then look at how to select another C++ compiler on the system to build our project, as well as outputting properties such as its path, ID and version.These settings are then used to compile the sample project included with this tutorial. Inspecting the Default Compiler This section details how to find out which compiler and compiler flags CMake uses on your system by default.We will progress in incremental steps as described below: This tutorial details how to inspect, configure and output a project’s compiler settings using CMake. It is also possible to configure the compilation process based on the host system’s environment in a granular way. The CMake program makes it possible to write simple configuration files to control a project’s compilation process and generate native build files across platforms. Separate development package or SDK, be sure it has been installed.Īnd you're wondering where it tried to find the library, you can use the undocumented CMAKE_FIND_DEBUG_MODE global variable for getting a more verbose output $ cmake -D CMAKE_FIND_DEBUG_MODE=ON.
To a directory containing one of the above files.
Gives the some error like CMake Error at CMakeLists.txt:4 (find_package):īy not providing "FindXyz.cmake" in CMAKE_MODULE_PATH this project hasĪsked CMake to find a package configuration file provided by "Xyz", butĬould not find a package configuration file provided by "Xyz" with any ofĪdd the installation prefix of "Xyz" to CMAKE_PREFIX_PATH or set "Xyz_DIR"
Cmake verbose code#
If the following code (replace the Xyz with your library in question) cmake_minimum_required(VERSION 2.8) Please set BOOST_ROOT to the rootĭirectory containing Boost or BOOST_INCLUDEDIR to the directory containingĪnd you're wondering where it tried to find the library, you can check if your package has an _DEBUG option like the Boost module has for getting more verbose output $ cmake -D Boost_DEBUG=ON.
Unable to find the requested Boost libraries.
Gives some error like CMake Error at /Modules/FindBoost.cmake:1753 (message): If the following code (replace the FindBoost module with your module in question) cmake_minimum_required(VERSION 2.8) CMake internally supported Package/Module The following examples just demonstrate more verbose CMake find_package() outputs. Note: The shown CMake error messages already include the fix for "non-standard" library/tool installation paths.
