[CMake] Python project using Cmake

[Matthew Keeler]

What are you trying to do? Are you trying to build Python C extensions? If so then the FindPythonLibs module will help you in that regard. It will determine if the Python development files are installed and populate variables with the necessary paths to provide to link_directories and include_directories. https://cmake.org/cmake/help/v3.3/module/FindPythonLibs.html

Additionally there is the FindPythonInterp module which will find the Python interpreter for invoking via custom commands or execute_process.
https://cmake.org/cmake/help/v3.3/module/FindPythonInterp.html

Also if you aren’t actually compiling any C/C++ code it will speed up build system generation if you specify the languages as NONE during the project command invocation. That behavior is documented at: https://cmake.org/cmake/help/v3.3/command/project.html

In the past I have used cmake even for pure Python projects to just get the benefits of generic packaging with cpack and to be able to use ctest. If this is the case for you then you may end up defining a bunch of functions/macros to do all the work as I did.

Hello All,

I am new to cmake and its build and ctest system. I read some where that cmake default look for c++ compiler and we need to modify/configure the cmake to recongize the python files.
I googled for the same but I couldn't find any concrete and complete example.
Any pointers in this regard would be useful.

Thanks in advance.
