Re: [CMake] Python project using Cmake

[Matthew Keeler]

Sorry Srinivas, the projects was for a former employer of mine and I no longer 
have access to it. We were distributing “scripts” as executable zip files (a 
lesser known feature of Python). So we had a few things going on.

include(FindPythonInterp)
configure_file(${CMAKE_CURRENT_SOURCE_DIR}/setup.py.in 
${CMAKE_CURRENT_BINARY_DIR}/setup.py @ONLY)
add_custom_command(${CMAKE_CURRENT_BINARY_DIR}/ COMMAND 
${PYTHON_EXECUTABLE} ${CMAKE_CURRENT_BINARY_DIR}/setup.py bdist -format zip 
COMMAND …)

For the add_custom_command we ran more commands after invoking python to run 
the setup.py file. The extra commands were to rename from the normal distutils 
name to the final name and to prepend a UNIX #!/usr/bin/env python text line to 
the zip file. In this way you can make a self contained “executable” that on 
UNIX at least runs like any other binary.

All of the add_custom_command logic to build these zip executables was put into 
a cmake function:
https://cmake.org/cmake/help/v3.3/command/function.html

If you do go the function route I would recommend taking a look at the 
CMakeParseArguments module it was very useful for me.
https://cmake.org/cmake/help/v3.3/module/CMakeParseArguments.html

Sorry I don’t have more specifics.

Hi Matthew Keeler,

Thanks for your quick reply. My project is a pure python project. I wanted to 
use cmake and ctest for testing my individual python modules. Later on, I might 
have some "tcl" scripts and may be some c++ sources in the same project.

It would be great, if you could share your pure python project details and the 
macros or related documents.

Thanks and Regards,

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.

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
