WHY NO REVIEW YET
TopGit writes full reviews for the most-starred, most-requested repositories. This page is a snapshot until then — see the READ ME tab for the original README in full.
Every CMake project requires a call to cmake_minimum_required to set the minimally required CMake version. However, CMake gives no guidance what this version may be, and a lot of projects just take the current CMake version or whatever the IDE is proposing as default. This is a problem, because some platforms don't always provide the latest CMake version, and a lot of trial and error is needed before projects can be used.
cmake_min_version is a script to determine the minimal working version of CMake for a given project. It does not do any magic, but just performs a binary search using a pool of CMake binaries and basically implements the "trial and error" in an efficient way.
Example
Assume ~/projects/example contains a project with a CMakeLists.txt file. Then the following call determines the minimal working version of CMake:
As a result, ~/projects/example/CMakeLists.txt could be adjusted to require CMake 3.8.0.
More options:
usage: cmake_min_version.py [-h] [--tools_directory DIR] [--full_search] [--error_details]
params [params ...]
Find the minimal required CMake version for a project.
positional arguments:
params parameters to pass to CMake
options:
-h, --help show this help message and exit
--tools_directory DIR
path to the CMake binaries (default: "tools")
--full_search Searches using a top down approach instead of a binary search (default: False)
--error_details Print the full stderr output in case of an error (default: False)
FAQ
Q: Isn't this a rather naive and inefficient approach to achieve the goal?
A: Yes, but I am currently not aware of a better one. I would be happy to replace this repository with a link on a tool that achieves the same goal.
Setup
In a nutshell
Install a Python virtual requirement (Python 3.6 or later).
The script cmake_downloader.py takes care of downloading CMake binaries:
usage: cmake_downloader.py [-h] [--os {macos,linux,windows}] [--latest_release]
[--latest_patch] [--first_minor]
[--release_candidates] [--min_version MIN_VERSION]
[--max_version MAX_VERSION] [--tools_directory DIR]
Download CMake binaries.
options:
-h, --help show this help message and exit
--os {macos,linux,windows}
OS to download CMake for (default: linux)
--latest_release only download the latest release (default: False)
--latest_patch only download the latest patch version for each release (default: False)
--first_minor only download the first minor version for each release (default: False)
--release_candidates also consider release candidates (default: False)
--min_version MIN_VERSION
only download versions greater or equal than MIN_VERSION
--max_version MAX_VERSION
only download versions less or equal than MAX_VERSION
--tools_directory DIR
path to the CMake binaries (default: "tools")
